Billy Quan was a fictional television character who originated in the Seattle TV comedy series Almost Live!
The general format of the skits, which averaged one to two minutes long, featured Quan being offended by the rude manners of another unnamed character, usually Almost Live!
The skits would usually end when Quan would launch himself toward Keister in a preposterous two-legged martial arts kick.
Quan's legs would stay in the air and follow Keister, sometimes around corners or waiting outside of doors.
The voice and mouth movements of the characters were greatly out of sync, a reference to some of Lee's early martial arts films.
