An English Gentleman travels to the USA. He and his wife want to travel cross-country to see the states.
They stop in a little diner and are just ordering when a huge biker walks in. As he walks past their table, he lets fly a loud nasty fart.
The English Gentleman jumps up into a fighting position and yells "How dare you fart before my wife?"
"Chill out little dude. I didn't know it was her turn."
