Scooby Doo!

A conversation/song heard in the back row while driving in the van:

Haley: Scooby, Scooby Doo, where are you? You've got some work to do now (sung almost perfectly).

Shanna: Scooby, Scooby Doo, where are you? [something something something] (not that close - close enough you can tell what she's singing, but obviously wrong).

Haley: No, not like that, like this (and she sings it again).

Shanna: Oh, like this? (and she sings it wrong again).

Haley: NO Shanna! Like this: (she sings it perfectly).

Shanna: Like this? (and she sings the the same way she's been singing it).

This goes on for about 5-6 times when Shanna finally says: I can't do it Haley.
