Punderdome: A Card Game for Pun Lovers

From BoardGameGeek:

One part game, one part conversation starter, you don't need to be a pun master to master Punderdome: the goal is to make bad jokes and have fun along the way. A player (the prompter for that round) draws two prompt cards from the deck, and then reads the prompts to the rest of the group, who have 90 seconds to create a single, groan-worthy pun that combines the two prompts. When time is up, pun makers share their puns with the prompter, who awards the prompt cards to the player whose pun he or she likes best. The winner then draws the next pair of prompt cards and the process repeats. Players win by obtaining 10 pairs of cards.
