Shitty Bum

A young man listening to dance music on his headphones suddenly finds a mysterious graffiti streak attached to his hand. It's bad stuff, he tries to shake it off, but it pursues him down the stairs and out in the street, stopping to complete a tag on an alley wall. We cut to a scene of a group of young men standing on the banks of a canal. Suddenly they break into synchronised disco moves, while a caption in large print, accompanied by a robotic voice, announces that it's time to get funky fresh.
