S4·E56 The Neitherworld's Least Wanted

Four of Beetlejuice's worst enemies--and LipScum--are organized together by a mysterious gangster named Mr. Big who's got BJ's number. His plan: trick BJ into separating his body parts and be unable to reunite them, until sundown does its dirty work (in case you didn't know, not only does BJ lose all his powers if he's fallen apart, but if he's not all back together by sundown, he's as good as exorcised. (Obviously a rule they made up just for this ep but I like it anyway.) Naturally, Mr. Monitor is on the scene to gather ratings.
