keep the rubes confused

When wanna-be actors have too much time on their hands you get... Improv Everywhere, an ad hoc group of wacky people who go on daring and hilarious missions around New York City. Their motto: We cause scenes. (Found on The Museum of Hoaxes.)

My favorites on their website, with lots of pics, funny quotes from the rubes, and even videos:

Store-front mass dance featuring "Agent Mason," which is not me. Fuck. My name is getting way too popular.
