Plot hole: The history on Urkel's Isetta is all wrong; in one episode he mentions that he paid $4 for a sunroof that he claims he bought used, however his uncle paid him $50 to take it away. In another, he claims his car has a speedometer that goes up to 30, but before it had a chalkboard. In "Hot Rods to Heck," the speedometer goes to 60 mph. The car would also screech, putter, sputter, smoke, break down, etc. but it seemed to be just fine in "Driving Carl Crazy," ''It's Beginning to Look a Lot like Urkel," and "Hot Rods to Heck."

Continuity mistake: From the outside of the house, you can see the staircase and door are to the far left of the house. But from inside the house, you have a fireplace and the staircase to the right of the door. So you know it's not the same house they use in the show.
Carl: Go home! Go home! Go home!
Steve: I don't have to take this. I'm going home.
Trivia: When this show first went into syndication, a market in New England declined to pick it up, thinking it wouldn't be popular with their demographics. They ended up providing the show for free with the agreement that the market would end up paying for the broadcasting rights if the show reached a certain ratings threshold.
Question: Is it true that the show's set was burned down? Either way, why was the show ended so suddenly (before Laura and Steve's wedding was even shown)?
Answer: It was just cancelled. Read more here: http://www.kellie.de/end.htm.
