Thief

The thief in the pilot episode of the show, To Catch a Thief, was known to break into people's houses at night and steal what he liked, similar to the stereotypical burglary. When William Missionima and Teddy moved to Jeb-an, they became the next victim. The thief is also known to be a murderer, as he killed an innocent man named Harry who had caught him breaking into their house. He had sneaked through the vents, and when he exited, he blew the bathroom up and killed Harry in the process. He was found in the sewage system the next morning, allowing William to attack him. As an act of gratitude, Mark the Mailman gave William the chance to compete on his favorite game show the next episode. The thief made a cameo in Mark & Mary Marry at the wedding.
