It's not a question of "would you do this and that for $x00,000", it's "will you".
All anyone who wants to be a millionaire has to do is get on craigslist and offer to fool around. You may not even have to have intercourse, just weird shit like smacking their genitals around with a piece of fried chicken, or chasing them around the subway station while wearing snakeskin boots, or say your ABCs backwards while they stick a video game controller up their ass. Weird shit like that.
