White Elephant (at least how we do it at work)
Everyone brings in a wrapped gift. Usually something tacky (under $20...)
Everyone who participates gets a #
Let's say 20 people are playing, everyone is numbered 1-20.
All #'s are placed in a hat.
Hat is passed and everyone takes a #, but doesn't disclose what it is. Keep that close to the vest.
Person who drew #1 goes first and gets to pick a gift out of the pile. Gift is opened.
Person #2 can either pick a new gift (and open it) OR take the gift from person #1
Person #3 can take a new gift (and open it) OR take either gift from person #1 or person #2
This goes on and on.
Bottom line, the higher your number, the better.
Game is a lot of fun and there's usually non-stop laughing.
