Another youth work classic.

Split your group into 2 teams. The leader will give a command ‘Bring me a…’ and the first time to bring that item to the leader gets a point.

This game can last as long as youth like and you can ask for whatever you like (on residential you can ask for toothpaste, make-up etc.). My personal favourite is to ask for a shoe-lace not attached to a shoe and then ask for the same lace back on the shoe!
