When I was in high school, we had this kid named Mikey who was the resident 'Jacka**' of the group. He was the guy who'd do literally any stupid thing you told him to, especially with any amount of money on the line. He once licked a cow heart we were dissecting in biology class just because someone paid him (I s**t you not) all of $3 to do it. Now, Mikey didn't just like doing dumb stuff for cash
though - oh no, he was more than happy to do it for free too, just to prove to everyone that he could.
Personally, I've never really felt the appeal of that school of thought, but as this thread shows, there are PLENTY of people who have.
