Moby Richard - S4.E44

Beetlejuice and Lydia put on 'Disasterpiece Theatre,' and decide to do Moby Dick as their first episode. But Moby ""Richard"" refuses to change the classic to suit Beetlejuice's notions of what a classic should be, and quits--but not without insulting BJ first. BJ lets the character of Captain Ahab take him over, and leads the others on a dangerous mission through Sandworm Land to get revenge on the whale.
