Honestly, he shouldn't have been a character in the prequels at all. The screen time he had in AOTC was just embarrassing, especially his lines. "What a drag!" "I'm quite beside myself!" I'm a fan of puns myself, but there was just no subtlety there. The only way they could have made it more obvious that the point was, "Hey, we're telling a joke! Laugh!" would have been if the words "CUE LAUGHTER" had flashed on and off on the screen in big red letters while he was saying that.
