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!

When mom walks in on 12th minute mark
...I thought the title said "organisms" but I watched this anyway
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"...
She has a very open, down to earth, playful personality and shows intellection curiosity. It makes her very likable and attractive.
Katniss Evergreen
This is the last subject I expected a TED talk to be on but I love it
this video really wasn't what it was advertised as
How did I end up here???
A Cappella Trudbol
I love Mary Roach!

This woman is amazing.
Abhishek Singh
this video is so funny, made me laugh so much.
I like this lady a lot. I want to be her friend.

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!
Other than perversion, titillation, and juvenile "jokes", there really was no point in this.
Jonjo Senna
Is it just me. Or is she got a sexy smile?
cezar t
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?
NOW I understand what was the lazarus project in mass effect series!
Hugh Jass
I bet she's a squirter.
Curt Shaw
5:41 #4 isnt freakin rocket science!  50% of my orgasms give my wife bad breath and it doesnt take an hour to do it!
Tej DIvadkar
She has like a glowing Hotness.
Beautiful Siren
Don't watch the whole thing unless you wanna see a pig get fisted
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).
well, that was thoroughly entertaining.
Luke Dillon
TED is so random, one minute ago I was watching a TED talk about photo manipulation and now...now I'm watching this
8:30. Ms Roach mentions pre-intercourse activity pertaining to the female. This we could presume has to do with the fact that usually, under "normal" circumstances, if left to their own devices and if both the male and female in a heterosexual situation do whatever they want to do to try to achieve orgasm, that he'll come first. Which is to say, if he goes to town and she goes to town, his orgasm will happen sooner. Could there be an evolutionary answer or explanation as to why this seems to be a universal truth? Noted anthropologist and sociobiologist Sarah Blaffer Hardy thinks there is. Or at least she did think so back in the early 80s when she penned "The Woman Than Never Evolved." In that seminal research, Hrdy followed and interviewed so-called ladies of the night and Australian Aboriginals, noting that there is a cumulative "stockpiling," as it were, of sexual pleasure in women, and that if a given woman jumps from one bed to the next to the next in rapid enough succession, that after four or five "normal" boinkings*, that she'll reach sexual climax; both female Aboriginals and female prostitutes were seen and admitted to lining up a series of men to do just that, making sure to not let too much time elapse between sexual encounters. So if Darwin's theory of evolution is not just a good theory, but it's a great theory, wouldn't it be able to explain more than the length of a giraffe's neck? Like it could also explain behaviors? Could evolution also explain why it almost always takes longer and more stimulation for a woman to come than for a man to come? Professor Hrdy thinks evolution can explain this sexual timing difference. At one point in our development the need for all women to reproduce as much as possible must have become a critical necessity. Say a woman was monogamously tied to one man only, and then her daughter was similarly monogamously tied, because of cultural customs or for whatever reason, and then her granddaughter, same thing, and then her great granddaughter, same same, etc. etc. Now as Nature would have it sometimes some of us are infertile. And without modern science our early ancestors couldn't tell who was fertile and who was infertile. Many a man can come like a fountain, but his sperm are either dead or nonexistent. If that infertile man were monogamously tied to one woman only, and she's fertile, well, she wouldn't reproduce. Nature had to eliminate that kind of monogamy way back when. Here's how Nature did it: all those women who were satisfied with what one man could give her in the bedroom eventually went extinct; leaving us with only those extra horny women. And how do you create these extra horny women? Make it so they can't come so quick. Light a fire under their hinder that makes them seek out multiple partners. What I'm trying to say is all those not very horny women who were satisfied with monogamy died off a long time ago; leaving us with only women who take a long time to come. LSS, men can be but don't necessarily have to be polygamous; women OTOH are SUPPOSED to be polygamous. It is a crime against our nature for us to be monogamously chained to each other. *by "normal boinking," in this sentence, I mean he just goes to town, like he paid for it, and he doesn't really have to please her, necessarily, and by doing something extra that allegedly helps her achieve orgasm, but neither speeds nor enhances his orgasm
Looking For A Name
She was very cool! You can feel her amusement at what she's talking about and it's contagious.
Wow, shes great and funny! This was informative!
Gwen M
this was a disapointing ted talk, I enjoy learning and this seemed more like a college paper for school not really a ted talk that made any kind of impression on me.
I can tell she had fun doing this one.
12:15 i'll never complain about my job ever again
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.
This is what Ellie Goulding will look when she grows old.
Iqbal Dinho
Considering the rather raunchy topic, Her delivery and presentation is excellent
Sean Hamilton
Bet she's so good in bed
Very Stupid Channel

Damian De
Who knows? Maybe the guy was married to a pig.
John C
Very interesting. Many thanks, Mary.
Scott Wheeler
Cheese crumbs will distract the female but not the male! This sort of sums up all human relationships!
That sow video is absolutely appalling :(
the teeth brushing reminds me of nisemonogatari, anyone?
Chris Carr

the audience very much lack sense of humor.
Thomas Lehmann
Love it! :D
Chandra Dickinson
I love this TED Talk lol
6:14 - nope, I'm out. That's enough youtube for today
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.
Embracing The Madness
my favorite part  "Now you have an evolutionary excuse" hahaha
