For that matter, the entire chase scene with Edgar and the dogs.
Even better, the scene when Edgar returns to the countryside to recover incriminating evidence from them. Hilarity Ensues.
When Edgar sneaks out of the house with the cats in the first place. He gets "held up" by a tree branch, notices that he's approaching a police station and promptly hauls ass in the opposite direction, and accidentally rides into a subway tunnel.
