This may take a while depending on the number of guests, but as you're waiting for dinner it's fun!
"Two truths and a lie."
Have everyone prepare in advance because for the "thinkers" of the group it always takes a long time.
Go around the table and have everyone tell their two CRAZY/FUNNY truths and ONE LIE about themselves. Everyone else guesses which one is the lie. You REALLY find out some funny stuff about everyone!!! (Everyone votes on which they think is the LIE and then you reveal.)
I just handed out an index card with the instructions printed out on it a day in advance so everyone could prepare & ponder before we did it. That way there was no scrambling to come up with something. You could do it at Church the week before or even email it to the guests.
It's hilarious.
Here was mine:
I cannot do a cartwheel. (Truth)
I broke my leg in a graveyard. (Truth)
I have eaten armadillo... and liked it. (Lie)
Have a great party!
