Martial Arts

I was standing at the bar of Terminal 3 International Airport when this small Chinese guy comes in, stands next to me and starts drinking a beer.
I asked him, “Do you know any of those martial arts things, like Kung-Fu, Karate or Ju-Jitsu ?”
He says “No, why the Heck did you ask me that? Is it because I am Chinese? Are you a racist?!”
“No”, I said, “It’s because you’re drinking my beer, you little prick.”
