Hilariously disturbing.

The rest are equally screwed up, and funny, as well...

The 6 Biggest Dick Moves in the History of Science - Page 2 | Cracked.com:

"...In 1954, two scientists named James Olds and Peter Milner found the pleasure center of the brain, dubbing it "Engorgeopolis." [citation needed] They theorized that they could stimulate this area by administering an electric current, and tested their hypothesis by wiring up a rat's brain and providing the little guy with a lever to control the shocks. Soon the rat was banging on the lever up to 2,000 times an hour, missing work, skipping meals and losing its temper with the children.

In 1970, Robert Heath of Tulane University refined the Olds and Milner discovery to test his theory of reversing homosexual behavior through pleasure center stimulation. That's right, Heath wanted to zap the gay away. Unable to locate a readily available supply of gay rats for his experiment, Heath went ahead and found a homosexual male's brain to dig around in.

The subject, B-19, was hooked up just like the rat in the pleasure study. At first Heath administered controlled amounts of stimulation himself, but then handed the pleasure button off to B-19 and allowed the subject to be the lord of his own electric bonerjam.

And stimulate he did. In one three-hour session B-19 pressed the button 1500 times until. According to Heath, "he was experiencing an almost overwhelming euphoria and elation and had to be disconnected." At that point, we're amazed his dick hadn't burst into flames.

Heath's theory was that B-19's sex drive would be so jacked he'd have sex with anything, and for Jesus' sake, why not make it a girl? This being 1970, this was clearly the part of the experiment where you bring in the whore.

When introduced to the female prostitute, however, B-19 did nothing for an hour until the prostitute initiated a sexual encounter herself. Nevertheless, Heath called the experiment a success, having proven that with enough electric shocks directly to the brain, a gay man will have sex with a woman as long as he's locked in a room with her for an hour and can't leave.

And that's why there are no more homosexuals around today."
