Quote from Reese in Malcolm Babysits
Malcolm: You butt-wipe, that's my toothbrush. Reese: So use mine. Malcolm: You can't just take someone's toothbrush. Give me that. Reese: Fine. [Reese walks over to the toilet and drops the toothbrush in the bowl] Reese: Oops. [Malcolm squirts toothpaste over Reese]
