Top 20 most bizarre experiments of all-time

Museum of Hoaxes has a run-down of 20 cruel and/or unusual experiments performed on both man and beast. They're from a new book, Elephants on Acid and Other Bizarre Experiments, by Alex Boese.
#18: “Would You Go To Bed With Me Tonight?”

If you were a man walking across the campus of Florida State University in 1978, an attractive young woman might have approached you and said these exact words: "I have been noticing you around campus. I find you to be attractive. Would you go to bed with me tonight?"

If you were that man, you probably would have thought that you had just gotten incredibly lucky. But not really. You were actually an unwitting subject in an experiment designed by the psychologist Russell Clark.

Clark had persuaded the students of his social psychology class to help him find out which gender, in a real-life situation, would be more receptive to a sexual offer from a stranger. The only way to find out, he figured, was to actually get out there and see what would happen. So young men and women from his class fanned out across campus and began propositioning strangers.

The results weren't very surprising. Seventy-five percent of guys were happy to oblige an attractive female stranger (and those who said no typically offered an excuse such as, "I'm married"). But not a single woman accepted the identical offer of an attractive male. In fact, most of them demanded the guy leave her alone.

At first the psychological community dismissed Clark's experiment as a trivial stunt, but gradually his experiment gained first acceptance, and then praise for how dramatically it revealed the differing sexual attitudes of men and women. Today it's considered a classic. But why men and women display such different attitudes remains as hotly debated as ever.
