S4·E34 Time Flies

It's the anniversary of the day BJ and Lydia met, and BJ presents Lydia with a watch. But time flies, and Beetlejuice and Lydia follow the escaped watch through the Sands Of Time, where they meet Grandfather Time. BJ gives the poor old geezer a cog-attack, thoroughly messing up the flow of Time. They must get Time restarted or nothing will be the same again.
