Have you seen this? The Pink Prank Project. This guy goes to NY for a weekend and his friends wrap up everything in his flat. In pink. Everything. According to the web page they put up to document it, 5 people, 6 hours, 203 meters of pink paper, 271 items wrapped.
This is so much better than the practical jokes I remember from college. Only back then were were a bit more incognito. No web...no YouTube to document our successes.
