The Madness of King Bob - S4-E9
Corrected entry: Near the end, when TJ is pranked, King Bob says, "You there, the behatted one," meaning TJ has a hat on, and TJ is who he wants as a volunteer. But the prefix "be-" means "not" or "de" (Think beheaded=no head), meaning TJ does not have a hat on.
Correction: "Be" doesn't always refer to "not". Think of befouled (made dirty) and bespectacled (wearing glasses).
