As other people have said, this is a potentially hilarious game, best played drunk with friends with depraved/dirty minds.
Can get boring after 30-40 minutes, and some rounds none of you will come up with a particularly funny set of cards and it will be a bit like a comedian with terrible jokes...
Worth playing, but I HIGHLY recommend reading through the cards before dishing them out to your friends. One of the cards reads: "dead parents", and if a friend has a parent who has recently deceased then the game stops being funny immediately.
Just a warning. Play with caution!
