Give each Scout a brand new clean white t-shirt from the packet. Over a period of time either incident hike or campsite afternoon activity, or even over a day, they have to keep it as clean as possible. Could be run as a wide game.
Penalties or forfeits for anyone caught messing other teams t-shirts.
Run various challenges and games that ensure t-shirt might or might not get messed up.
