I thought this joke was quite clever.

I was sitting at a bar last night and this Asian looking fella sits down next to me and takes a sip of beer.
I glance over at him and ask if he knows any of those martial arts like Kung fu, or Karate or Ju Jitsu.
He says, "No, WTF man!? Are you asking because I'm Chinese?!"
I said, "No, it's because you're drinking my beer."
