Karate vs. Banjo

I just approached my co-worker Min Ho in the hallway, and for whatever reason I felt the need to do a series of karate kicks in his general direction.

He stopped.

Then he looked at me funny.

Then we had this exchange:

Min Ho: "Are you assuming that I know martial arts because I'm Asian?"
Halee:   "YEAH!"
Min Ho: "Okay, then I guess I'm bringing you a banjo tomorrow."
