Not a joke, but there's a Russian kid in my physics class. He was doing a presentation about nuclear bombs in Russia, and was trying to explain why some scientists were afraid of messing up calculations or something like that. He said with his heavy Russian accent, "In Soviet Russia, if scientist mess up, secret police come to house and take him, and kill family." While this is sad because at some point in Russia this was probably true, i laughed my ass off for the rest of class.
