Daddy Roulette
A guy goes around having sex with multiple girls, and he doesn't care if he ends up with a bunch of kids because he's too busy having fun.
My dad had sex with three different girls and didn't care if he ended up with three kids.
My uncle had sex with five different girls and didn't care if he ended up with five kids.
My cousin had sex with two different girls and didn't care if he ended up with two kids.
