The game goes like this, one person asks a question then the other answers in a pun (simple a?) Ex. How did Michal Jackson die? Answer : IT was a thrilla night when he said BeAT IT just BEAT IT to Lady Gaga then Poked-her-face so she ran him over with flow rider.
Long example, but it can be shorter and have better puns...
First question: Why did the man throw a clock out the window?
