Five or six fishermen sit on the end of the dock (chairs), casting and winding in their lines. One fisherman is catching all the fish: the others have no luck. In turn, the unlucky ones ask the successful fisherman why he's doing so well. Each time, he mumbles a reply without opening his mouth, and nobody can tell what he is saying. When the last person asks the question, the successful fisherman sighs, spits into his hand, and says, "You have to keep the worms warm."
