There's a kind of funny youtube hidden camera prank wormhole I got caught in the other night. Search "killer clown prank" or something along those lines and there's a series of videos in which a pretty impressively creepy looking clown happens upon people in parks or empty parking garages or wherever and freaks them out. One in which he walks up to a guy at a gas station and just starts dumping liquid from a gasoline canister in a circle around the guy's car. Some of them are actually quite mean.
Maybe disregard that sage advice as I just searched YouTube and didn't find the relatively lighthearted and funny videos I was seeking from earlier. Over the top and crazy, ridiculous crap abounds. Gah.
