Plot hole: On the episode "Scenes From A Barbecue", all the kids and Arnie are about to play a basketball game. Darlene and Chuck Jr. battle in Rock, Paper, Scissors to see who picks first. They both throw scissors, and then Chuck Jr. says he gets to pick first. They should have done it over, since that would be considered 'a tie', he really didn't win.

Continuity: In season 7, episode 24, "Couch Potato," Roseanne brings in a plate of sandwiches after Dan brings home the new couch. She places the plate on the the small stand in front of her. Between shots, the plate switches to the stand in front of Dan and then back to in front of Roseanne.

Continuity: During season 1, episode 6 "Lovers's Lane", Dan tells Crystal that his shoe size is size 11. Later in the same season, during episode 16, "Mall Story", Dan tells a shoe salesman he takes a size 13. Dan's an older guy and his foot size would not grow during the short gap between the episodes - the first took place during Fall and the second took place during Spring.

Continuity: In "Guilty By Suspicion," Jackie hangs up her coat in her living room closet. This is the same door that, when she first moved into the house, led to the basement.

Other: When the opening credits are shown, the door to the basement is in the kitchen. In the beginning of the series the door is still in the kitchen, but in later seasons the basement door is in the laundry room, but in the opening credits it is still in the kitchen.

Continuity: In season 1, episode 19 "Workin' Overtime" - Roseanne comes home and the kitchen cabinets are not painted/plain wood. In the very next shot from a different angle, the cabinet doors are painted.

Continuity: In the first episode that Darleen's boyfriend (later her husband) appears, he is introduced as "Kevin" Healey. In all future episodes his name is David.

Continuity: In episodes when Darlene has just moved into her apartment, the bathtub is on the wall in front of the bathroom door. In later episodes, the tub is on the wall to the left of the door.

Continuity: Over the course of the entire show, the entrance into DJ's bedroom changes position. In the earlier seasons, the entry was on the right-hand side of the screen and the bathroom door was to the left. In later episodes, the characters entered the bedroom from the left-hand side. Everything else in the room remains the same.

Continuity: In one episode, there is a bowl of fruit on the table in the living room. The boys start wrestling and they knock it down. In the next shot it's back on the table again, untouched.

Continuity: "The War Room" When a depressed Roseanne emerges from her bedroom after Dan has left her, she tells Nancy and Leon that she wants to turn over her and Jackie's shares of the restaurant to them. She says she wants Nancy and Leon to experience the same sense of accomplishment that she and Jackie felt when they first opened the business. However, Roseanne seems to have forgotten that it was Nancy, along with her, Jackie, and Bev, who started the restaurant.

Revealing: In the episode "Home for the Holidays", when the family is eating the Christmas cookies, look at the top of the screen. In the kitchen, you can blatantly see where the top of the kitchen actually ends, revealing gray panels. The Conner's ceiling never went up this high, so it is definitely set material.

Continuity: In "The Birds and Frozen Bees," Roseanne and Darleen are sitting on the sofa discussing Darleen getting back together with David. The cuff on the sleeve of Darleen's sweater is partially turned down, and in the next shot it's neatly turned up.

Continuity: During the show's first two seasons, we are told Roseanne had a more slender figure during her younger years and didn't start gaining weight until after she began having kids. Later in the Halloween episode, "The Ghost of Halloween Past," Roseanne is shown her past, and her younger versions are not slender.
