Go to friend:
Me- I'll give you 50,000 if you let me pee on.
Friend- wth is wrong with you
Me- I'll get a hundred grand if I piss on my best friend. I'm essentially splitting the money with you.
Friend- dude hell yea let's do it.
Me- ok but don't look at me. I can't go if your watching.
Moral of the story a friend would be more inclined if they feel that your splitting the money.
