You could make it a quiz as already suggested and make up punishments for wrongfully answered questions, like:

Pop waterballoons above eachothers head.

Spin a wheel which indicates what should be done and where, a sort of twister.

"pop a balloon above the right leg, pour a glass of water on the head"

If you want to make it more embarrassing, fill the balloons up with custard or water with food colouring and wear all white.

If the weather is good, push eachother in a river/pond/pool/fountain.

Try to wash eachothers hair while clothed but try to keep as dry as possible (or not).

Jump into muddy water and do a walk of shame to your house.

Let me know what you like, maybe ill come up with more.
