(Malcolm hears girls screaming and giggling, then sees bikinis floating in the water, he picks one up and looks at it)
Hal: (picks up a pair of shorts) Huh, is this your brother's shorts?
(Malcolm gets shocked and starts the speedboat and sees Hal holding on to the boat as it goes, he slows down and stops the boat)
Hal: (hanging onto the boat) Why?
(Malcolm kicks Hal off and takes off)
Hal: YOU ARE IN SO MUCH TROUBLE!!!!
Malcolm: (to the camera) I can't believe it either!
