Man goes to a petrol station. It's night time and one of those serving hatches. Talks to the girl. Can I have a can of coke and a Kit kat Chunky? Off the girl goes to get his stuff. ""There you go,"" she says, ""One can of coke and a KitKat Chunky."" ""No,"" says the man, ""I wanted a normal Kitkat, you fat cow.""
