The Married With Children "It's A Bundyful Life" Christmas Special!

[That Other Guy]

The name "Toaster Leavin's" (Leave-ins?) comes from a later episode where TV execs make a TV show based on the Bundy's lives.
Al's failures? Sometimes his misery is his own fault (any handyman task he attempts), but he is usually being screwed over by someone else (Marcy and her co-workers, in this case) or often by the universe or some facet of "the Bundy curse".
