Continuity mistake: When Roseanne & Jackie talk about Arnie, they act like they haven't known him long. Jackie even states, "I don't know him." Yet, in episode "Why Jackie Becomes a Trucker," Jackie sleeps with Arnie. Roseanne says all the girls made a pact in high school that none of them would ever sleep with him.

Factual error: When Becky locks Roseanne out of her bedroom, Roseanne heads to the garage for a screwdriver to take the door off the hinges - an impossibility since the hinges are on Becky's side of the door. In the next scene, the door is off the hinges.
Suggested correction: Roseanne could have waited until Becky opened the door at a later time. She would have to come out at some point. Dan could also have ordered her to open it, and Roseanne then took it off the hinges. It was also Darlene's room, so Becky would have to let her in. Roseanne was making a point and to make sure Becky didn't do it again.
This is the most ridiculously convoluted "correction" ever. It was a monumental mistake, or at the very least, they hoped viewers wouldn't notice.
Yeah, not an impossibility whatsoever considering even if the door had to be forced open, it was going to be taken off the hinges. Classic 80's/90's parenting.

Continuity mistake: When Roseanne starts to serve the plates of food at dinner, she hands Dan the first plate, but DJ already has one. When she serves the second plate of food and gives it to Darlene, a plate of food can be seen in front of Becky.
