Uncle Buck Day Continues

Buck: Did you brush your teeth?

Miles: Yeah. You can even feel my toothbrush.

Buck: You know, I have a friend who works at the crime lab at the police station. I could give him your toothbrush and he could run a test on it... to see if you actually brushed your teeth... or just ran your toothbrush under the faucet.

[Buck leaves, as Miles gawks]

Maizy: If that's true, we're gonna REALLY have to start brushing our teeth.
