RENEE MONTAGNE, HOST:
Good morning. I'm Renee Montagne. It's such a guy thing - drink a lot and relieve yourself on a building. Germans have a word for it - viel pinkeln. And now in Hamburg's nightclub district, a solution - a new high-tech paint that is so waterproof, any spray on the wall bounces right onto the source. The paint has been applied to a couple of buildings and drunk night clubbers have been warned. One sign says don't pee here. We pee back. It's MORNING EDITION.
