Dear John (1988)

S4E11 'Twas the Fight Before Christmas

John unknowingly hires a troubled Santa Claus to entertain the kids at the day-care Christmas party. The man shows up in a shabby suit, clearly nursing a few too many eggnogs, and his ho-ho-hos come out slurred. Between losing his fake beard and getting tangled in the Christmas lights, he turns the festive event into a chaotic mess. John quickly realizes this Santa needs more help than he can give, leaving him to juggle damage control and holiday cheer.
