I always thought the "2 Truths and a Lie" was fun. You all write down on a piece of paper two things that are true about yourself and one thats made up - like "As a baby, I learned to walk with casts on both my legs" or "I hate the taste of water" (those are two of my personal favorite truths to use
) And then when you read it to the group, they have to guess which one is the lie.
Its a fun way to find out some quick, wacky things about each other, and people get either really creative with the lie, or appropriately boring (to match the theme of the truths).
