So this guy is standing in line at a concession waiting for the hot dog he ordered when a small Asian looking guy gets in line next to him and starts drinking a beer.
The guy look at he Asian guy and asked, "Do you know any of that martial arts stuff, like Kung-Fu, Karate or Ju-Jitsu ?"
The guy with the beer turns an says "No, but why would you ask me that? Is it because I am Chinese?"
"No", said the guy, "It's because you're drinking my beer, asshole."
