The engraved plaque on the Muhammad Ali letters presentation has a misprint. It says "JUST BEFORE HIS FLIGHT IN ZURICH" instead of "JUST BEFORE HIS FIGHT IN ZURICH".
Greg Grunberg introduces Rick to Tall Rob as the Hollywood expert who obtained the bust and mold of Bruce Lee's head for Greg. Rick then calls upon his own Hollywood expert Hal, who makes a very poor impression. In future episodes when Rick needs an expert in Hollywood memorabilia, he calls in Tall Rob, whom he met for the first time in this episode. Hal is never seen again in the series.
