Clown Fisherman

You are boating on a popular lake with some friends. You come across a nice man who is fishing by himself. Slowly drive your boat towards his and politely ask him if he has extra bait. Board his boat and chloroform him. Strip him and then dress him up in only a speedo. Paint his face so he looks like a sad clown. Handcuff him to the steering wheel and drop his anchor so he does not drift. For the rest of the day - anyone that comes near him will not take the cries for help from the old clown in a speedo seriously. Everyone will laugh - except for the clown.
