Overview: Blaine Cook, the owner of Zippy's Giant Burgers in Seattle, calls Charles Stiles to investigate rumors he's heard that his employee Aaron working as the costumed mascot Zippy the Yum Yum Burger Boy is misbehaving. The Mystery Diners go undercover and point to big problems when they reveal who was behind the whole misbehavior, Aaron's friend and roommate named Dopey Dan. He has been showing up intoxicated as a favor while Aaron visits his sick mother in secret to handle her errands. When the two are confronted, Blaine expresses his disappointment in Aaron for having Dan cover his shifts. Stiles asks Aaron why he doesn't have Dan take care of his mother's errands. Aaron stated that he wouldn't trust Dan to do any sort of errands for his mother. Stiles also points out that he made the mistake of trusting Dan to come to his place of work to cover his shifts and having him wear the Zippy costume while intoxicated.
