Bob's intelligence serves him in many ways. For example, during this episode, the parole board asks Bob why he has a tattoo that says "Die Bart, Die"; Bob replies that it is German for "The Bart, The." The board members are impressed and release him because "no one who speaks German could be an evil man" (an allusion to Adolf Hitler). However, his love of high culture is sometimes used against him. In the same episode, Bob agrees to perform the operetta "H.M.S. Pinafore" in its entirety as a last request for Bart. The tactic stalls Bob long enough for the police to arrest him.
