People shiver and complain about the cold water. Obviously, MTV doesn't think to choose engineers for cast members, because the whole boat-building task is a laughable failure. Instead, both casts utterly ignore the rules. No one receives a single lousy point. The object of this game is to knock an enemy team member off his intertube.
People tend to fall off without much prompting, however.
Their landlubber castmates shout directions at them. Lindsay and Dave pathetically tip their canoe. Lindsay complains of numb fingers. Two teammates scoop inflatable sharks from a jet-ski. Janet and Stephen again pathetically tip their craft.
