Jennifer Aniston revealed on The Howard Stern Show that a male guest actor on Friends had a terrible attitude and was disrespectful towards the cast and crew. Although he apologized years later, the actor thought he was too good to be on a sitcom and belittled the show's humor. Aniston expressed her disappointment, stating that Friends was a welcoming environment and that the actor's behavior was unacceptable. It remains a mystery as to who the actor was, but Tom Selleck was praised for his professionalism and kindness on set.
