Now that cat videos on YouTube are going viral, use this trend to play a fun game. Download several of your favorite cat videos (or clips) and load them onto a laptop that can be shown on a larger screen before your entire group. Divide into two teams. Half of the teenagers from each team then stand with their backs to the screen and must watch the other half of the group act out the cat videos they are watching. They must then try to guess what is happening in the cat video. Play like charades, with the teams scoring points who guess correctly.
