A guy walks into a store and asks the guy behind the counter
for Polish Ham.
The storekeeper asks him, "Are you Polish?"
The man is insulted. "If I came in here and asked for French
bread, would you have asked me if I was French? If I had asked
for German Bratwurst, would you have asked me if I was German?
If I had asked for Swiss Cheese, would you have asked me if I was
Swiss? If I had asked for Spanish peanuts, would you have asked
me if I was Spanish? ... So why did you ask me if I was Polish?!"
