What do Santa Claus and George Jetson have in common? They both have to work on Christmas eve! That mean old Mr. Spacely forces George to work late, while the family wonders what has happened to him, while Astro opens one of his presents early, breaks it, accidentally swallows a piece of it (a Spacely Sprockett) and becomes very ill. It seems the Jetsons may lose their Tiny Tim-like dog. Plus, Mr. Spacely is visited by his old partner, Jacob Marsley, who tells him of three spirits that will visit him. And they do, first the Past ghost robot who shows him young Spacely picking on young George, Present (which is an Xmas present) shows him of dying Astro, and Future shows the Jetsons very rich after sueing Mr. Spacely. When Spacely wakes up after seeing all this, he’s a changed man! A sadder, wiser, nicer and happier Cosmo Spacely! At least until the next episode.
