Adapted from "Busca tu cancion" in 101 juegos musicales. See also I second that (e)motion.
The joker writes down three to 10 emotions on index cards, two cards per emotion. (One set of three if you have an odd number of participants.) There should be as many cards as participants.
Shuffle the cards, keeping them face down, and have people pick a card, keeping it hidden from others.
