Morons from Outer Space

A space ship stops at an intergalactic fuel station. While the captain's refueling, one of his idiotic companions plays with the controls and accidently starts the ship and crashes into the earth. This causes a sensation: the media celebrates the extraterrestrials, the military interrogates them for eternal wisdom. However soon they recognize that the fellows are dumb as bricks - although some generals believe it's just a mask.
