Scratch Street

This just completely rules.

To steal Cory's description from BoingBoing:

Scratch n Spin is a very amusing short video advert that combines footage of a DJ's hands working on a set of turntables with footage of a streetscene; when he grabs a car and moves it around the roundabout, it is synched to the sound of the record from the original shot scratching back and forth. It's intensely clever and laugh-out-loud delightful.
