Mark, Dabbles and Joe are out fishing in a boat on a big lake when the Mark realizes that he has to go to the bathroom.
Not wanting to disturb the fishing of the others in the boat by having them take him to shore, he gets out of the boat and walks across the water to do his business and then returns to the boat.
A little while later Dabbles has to go also and he does the same. He walks across the water, does his business and returns across the water to the boat.
Finally Joe feels the urge to go to the bathroom too, so he climbs out of the boat. But instead of walking across the water, he falls into the water and starts to wildly splash around.
Mark and Dabbles finally drag Joe back into the boat and Mark turns to Dabbles and says, "Maybe we should have told him where the rocks were."
