He later made an appearance in Secrets of a Sucessful Marriage in which he is in the background of Homer's marriage class. He did not appear again until Who Shot Mr. Burns? (Part Two) where he made his only speaking appearance when he was thrown in jail for killing people and throwing them into Springfield Dam.
