This is pretty clever youth ministry icebreaker that I found while searching YouTube for some ideas.
Have two or more teams. Have them lie down on their backs in a long line (one persons head at the other persons feet). The person at the front starts with a banana in between their feet and must lift their legs up to pass it on to the next persons feet. The first team to get the banana all the way back to the end of their line wins!
Here's an example I found on YouTube.
