Jennifer Aniston recently revealed on The Howard Stern Show that a male guest actor on the set of Friends exhibited unpleasant behavior and appeared to be disinterested in being there. According to Aniston, the actor seemed to think he was too good for a sitcom and would make derogatory comments about the show's humor.

Although the unnamed actor later apologized for his behavior, Aniston's comments suggest that the incident had a lasting impact on her and the rest of the cast. Fans may never know who this mystery actor was, but Aniston made it clear that their attitude was not welcome on the set of Friends.
