had to step outside for a cigarette after the pig segment
She has a very open, down to earth, playful personality and shows intellection curiosity. It makes her very likable and attractive.

I brushed my teeth just in case but nope. nothing

TED is so random, one minute ago I was watching a TED talk about photo manipulation and now...now I'm watching this
Ste Dunn
I'm not the only person here that developed a crush on this woman? At first I didn't really think much of her, but as she spoke and her jokes, facts, intelligence shown, I thought wow she's really lovely, she's a true geek, that obscure thoughts, always the best type!
...I thought the title said "organisms" but I watched this anyway

Sick people laughing at animals being held captured by human beings.... and normalizing animals being sexually stimulated and inseminated by humans as if it was their job in the first place to do so. And for what?......... more pigs to be slaughtered for all the bacon no one really needs. It's just so sick!
This is what Ellie Goulding will look when she grows old.

11:25 that's enough internet for today...
11:43. Would gloves have KILLED YOU?? Seriously?? I'm done.

from finding tutorials on calculus to watching a man fist a pig. ._.
Joseph Davila
Like how she made an awkward talk fun and kinda hilarious.
Alison Lwin
'All animals are equal but some are more equal than others'. George Orwell. What that person is doing to the pig is unnatural and very wrong.
ok but while everyone is laughing at that guy arousing the pig, does nobody else feel sad and a little disgusted that the pig is being used just to be exploited :(

If all that .. intercourse makes the sow give birth to ten piglets instead of nine, does that means the guy is the father of the 10th piglet?

I had no idea that farming brushed up so closely with beastiality.
Justin Torres
The most useful piece of information I got out of this was that the current record for distance ejaculated is 8 feet.

Her face is adorable omg she's like the most entertaining person ever
Embracing The Madness
my favorite part  "Now you have an evolutionary excuse" hahaha 
Thank you for this great, entertaining and "unusual" lecture - very interesting facts especially for a society that has been so repressed (prude and Victorian) in its acceptance of sexuality as a normal human function (I am talking about the American society of "don't ask - don't tell, "... but I did not inhale", "... I do not have a sexual relationship with Ms. L...".  Great lecture, great video, great delivery style, thank you, Ciao, L
Monica Havemann
I like the term " A brain dead expert"...
Nancy Eves
I just don't know how the she and that entire audience can react so humorously to the sexual assult of an animal. Yes, that's what it is. "Artifical insemination" of farm animals is rape because humans should not be "pleasuring" or inserting parts of themselves into female animals' reproductive organs.
BooBoo Bear
12:00 And I thought my job sucked.
Kenneth See
This woman handled this so well. The audience needed to lighten up a bit...
Brenda R
Let's discuss what's important: those are ugly shoes and look very uncomfortable, but she does a good job of walking around in them. I would, at the least, step out of one and go flying.

Brynn McNeill
I was enjoying this video until the part about the pig. Not funny at all. The fact that everyone in the audience was laughing is so disappointing.
joseph reen
This lady is so beautiful
Jonathan Cy
She's a real Annie Hall type -- endearing, intelligent and a fantastic sense of humor.
Fábio van Tol
this is animal abuse 🤢
She's amazingly interesting and a brilliant presenter. I enjoyed that ;)
lol who else accessed this video expecting to see that nightmare from American Idol a few years ago?? The one who wanted to be called Mary Guilbeaux???
YiFang Wooh
i like her confidence, makes her speech so fascinating
Brad Neitsch
6% increase in pig production. Its not worth all that
Pink Panda
That would be a great Colgate ad
Beautiful Siren
Don't watch the whole thing unless you wanna see a pig get fisted
Alistair Drennan
She really reminds me of the actress and ex-SNL star Molly Shannon
This crowd was uptight, this lady is a great speaker
Firth Laist
Toothbrush Lady obviously had an Oral Fixation ....causing her "over think" the whole process ....I hope she Spits, rather than Swallows that dirty Toothpaste ; ) )
Shelby Thompson
Off topic, that's not okay to do to an animal??
This is sickening. Are we just supposed to be ok with this bestiality? Like seriously wtf? Not ok, not for breeding, not for anything.
She has such a stoner laugh
Chris Carr
masters and johnson. lol. could they have had better names!
Noah Williams
The whole "stimulate the pigs for better fertility" strikes as something that might seem kind of unethical (or at least too weird to consider).
Looking For A Name
She was very cool! You can feel her amusement at what she's talking about and it's contagious.
12:15 i'll never complain about my job ever again
Scott Wheeler
Cheese crumbs will distract the female but not the male! This sort of sums up all human relationships!
I can tell she had fun doing this one.
Hi, I'm Hot Rod
Why did I click this???
Lynn Gazal
Horrendous to make light of abuse of pigs like this. Heart breaking and truely sick.
This is sickening. Are we just supposed to be ok with this bestiality? Like seriously wtf? Not ok, not for breeding, not for anything.

lol, about the range of ejaculation, a huge factor is when you did it last time. hit the wall once (~1,5m from my pc) after not masturbating for over a week xD if the wall wasn't there, it would have been farther than 1,5 meters. what i want to say with that is that the guy who made the study back then probably didn't let them all ejaculate a day before testing, and those dudes were saving up for a different amount of time.
Mary Roach is the most amazing author. Unique, brilliant, and interesting; everything she writes is so funny and informative. Love her
i feel the earth moooove....
Carlotta Lanzani
great talk but why was everyone laughing at the video of the pig being abused - so messed up
this is like science stand up
Marble Grimes
I think she has a future in stand up
Damian De
Who knows? Maybe the guy was married to a pig.
Walks away giggling to herself 16:28-16:38
The fact that this has 5 million views says everything
saud abalkhail
I was eating when she showed the pig video. Nightmare
she's really awkward and doesn't speak well. what was the point of the masturbating fetus? she didn't elaborate on that at all. also it says "2. You don't need genitals" but there was no #1.
orla coghlan
It makes me so sad that everyone is just laughing at that pig being sexually assaulted. When did this become ok?
leave animals alone, don't you see how sick this is?
Vijay K
Am shocked that this video is on the TEd top shows. Nothing to learn and plain random talk. Very disappointing and a waste of time.

I just remembered i have to brush my teeth
Other than perversion, titillation, and juvenile "jokes", there really was no point in this.
She nailed this... Get it? "Nailed"
Ramdas Iyer
One of the most humorous and endearing persons I have ever seen lecturing.
Yes, Mary Roach is slightly demented.  She exhaustively researches really odd topics, and ends up writing fascinating books that go where few dare to go.  Nice to see her live, with a healthy sense of humor about all this strangeness.
Sumaiya Zaman
11:50 Ok. Enough. I'm out. Too much internet for a day.
Luke Yntema
All I've learned from this is how to get a pig off... I'm on the dark and creepy side of youtube.
Chandra Dickinson
I love this TED Talk lol
Kellan Evergreen
This is the last subject I expected a TED talk to be on but I love it
Penny Tennermann
Nice to see that she is as entertaining a speaker as she is a writer.
Jim Ronsivalli
I love her, she's smart, attractive and funny. My kind of woman.
Majid Hakak
The most funniest was upsuck theory...
David Cameron got a woody at the 12 minute mark.
Jedi Lady
The spinal she talked about is The Kundalini Awakening!!
Bruceann Yellowega
The pig video, all in the name of science. Yuck!
Wendy Parsons
Hearing "Dr." Kinsey mentioned 4x in this small clip makes me want to puke. That man's studies included child rape and molestation. I don't think that deserves any credibility whatsoever, unless it could somehow be used to try to find ways to keep mentally ill individuals from abusing children.
Jesse ___________
Somewhat entertaining, but not so interesting. The presentation could have been tightened and made to deliver some kind of message. She was basically all over the place and seemed like she just did it for a laugh, which may be why she came across as awkward and embarrassed.
gus dupree
let me guess, arousal is all in our minds,duh
Danni Liu
Did not prepare for the pig video. Slightly scarred.
That sow video is absolutely appalling :(
Rare Person
poor pig :( 11:34
NOW I understand what was the lazarus project in mass effect series!
Website guy
Could just let the pigs do it.
She lost credibility with me when she mentioned Kinsey.
The part with the pig was in bad taste. It's time we finally stopped abusing animals. Don't use "fun" facts about their exploitation for laughs.
Vyas Prab P
she looks like Nicholas Cage
I like this lady a lot. I want to be her friend.
i was alright until the pig vid :l
Alexandra Salazar
They basically sexually abused that pig 🐽
this video really wasn't what it was advertised as
Smid Dieus
if you ever need a research subject....I will make myself available...
TR Poole
Kinsey was a sexual predator himself hiding under the guise of "scientific discovery".
Funny! Well done.
the audience very much lack sense of humor.
