4. Das Baumhaus
A tree house is being built by the children - wooden clamps are needed to connect beams, but these were appropriated by two other boys to build a raft. Annoying, because the boys are on the pond with the raft. In order to get to the wooden clamps quickly, the other boys have to get naked and jump into the water to "board" the raft, which allows all the girls to see all the boys willies. The splashing is more fun though, so the wooden pegs stay where they are...in the raft.
