Two Truths and a Lie is the classic icebreaker game in which one attempts to identify which of the three statements is bogus.

Have everyone sit in a circle.  Each person prepares three statements about themselves, two of which are true and one which is a lie.  In any order, the person shares the three statements to the entire group.  The object of the game is to figure out which statement is a lie.  The rest of the group votes on each statement, and the person reveals which one is the lie.
