What an amusing turn of events.

Pericles.

Professor Pericles:
Don't be afraid, Scooby. I've no reason to hurt you. [holds up the piece] I have what I came for. [chuckles]

Scooby-Doo:
The mayor's piece! You have it!

Professor Pericles:
Two down, four to go. [opens the car window] Until we meet again, auf wiedersehn, Scooby-Doo.
