A patrol of scouts lines up, facing the audience. One announces that this is the Earwash Skit. At the end of the line, Scout drinks a glass of water. He puts his hands on his ears and shakes his head. Then he pretends to spit the water into the ear of the scout next to him. Repeat this process until the Scout at the end of the line shakes his head. This Scout spits out some water onto the ground.
This requires a scout who can hold water in his mouth and not be noticed.
