Continuity mistake: After Tim smashes Al's display cabinet, it cuts to Tim, then back to the workbench and the wrecked cabinet. The pieces of china and the pieces of wood on the bench differ in the two shots. In the first shot, there are two whole teacups, one whole plate and a bit of a shelf on the bench (the shelf is on the right side of the screen), in the second shot we see a broken tea cup, one broken and one whole plate, and the piece of shelf has disappeared.

1 continuity mistake in Bye Bye Birdie
Continuity mistake: This episode establishes that Tim is three years older than Jill. However, in the episode "Ex Marks The Spot" (Season 2), Tim said that he broke up with Stacy after high school, then met Jill at college. And Jill wouldn't date him unless he promised that everything was over with Stacy. If Jill is three years younger, she would have been only fifteen when Tim broke up with Stacy, not at college.

Al: Well, I'd have to say it's getting down and dirty with my hoe.

Question: Was the actor who played Cal Boreland really Richard Karn's brother in real life?
Answer: According to imdb.com: Richard has only one sister. http://uk.imdb.com/name/nm0439781/bio.
Answer: It should also be noted, Richard Karn is his stage name as Karn is his middle name. His real name is Richard Wilson. Cal was played by Keith Lehman.
Siblings can have different last names. One might have a different father. Maybe one legally changed his name for some reason, or a man took his wife's last name (not as common, but it happens). Of course, these two actors are not actually related, but I just wanted to point this out.
Answer: No the guy sent in a picture of himself because he thought he looked like Al. So they brought him on the show as his brother.
