The biggest McDonalds in the world, up until recently, is in Red Square, Moscow. Now if that isn't a scary sign of American cultural invasion, I don't know what is.

Personally, if I have a hangover, I can't wait to get to McDonalds, I'm fit, I'm healthy and in no way overweight. People aren't forced at gunpoint to go into McDonalds and eat there every day. I'm going with Ching Chong on this one. People have their own free will.
