This is a pretty cool social psychology experiment.. if a good-looking girl went up to random guys on the street and asked for sex.. how many do you think would say yes? Well, that exact scenario plays out in this YouTube video:
In case you didn't finish that video.. it ends up where about 50% of the men said yes.
So what happens if you reverse it and have a guy go out and ask the same question to a bunch of women:
He didn't have quite as much luck.. 0 women said yes.
