Over spring break or christmas break, one of my favorite things to do was to make drinking games out of the paternity shows. At least 1 was on a day, however there was on average 2-3 of them.
Everyone sits down, with a shot infront of them. You guess "Is the Father," or "Is not the father." You get it wrong, you drink.
Occasionally, they have on an episode where some girl brings in 3-8 guys to be tested at once. You can go out on a limb here, and bet who the father is before anything starts. If you get it right, everyone else drinks 3x ontop of what ever else they are drinking.
