Continuity mistake: When Summer is surrounded by the army and talking to the car, we see her seat has stuffing coming out of it on two spots. But shots facing her, you can see there's no stuffing coming out of her seat and it's the driver's seat that has the stuffing sticking out.
Continuity mistake: In the beginning, throughout the breakfast scene, items on the table change. For example, the cereal box position and at one point Morty puts his fork down next to his plate by the edge of the table, but in some shots it's not there.
Continuity mistake: When Rick, Jerry and Beth are eating pancakes, Jerry has his fork in his, but when Morty walks into the room and Jerry mentions science fairs are a father/son thing, Jerry's fork is suddenly on the table beside the knife. A further two shots after, the fork is suddenly back in the pancakes.
Continuity mistake: The garage door is broken at the start of the episode, dissolved partly through and falls down. Then at the party, an exterior shot shows the door fine and intact once more, but moments later when Morty is in the garage with a girl, the door is broken again.
Continuity mistake: Morty is digging through a locker that is among a set of six other locker doors, the one Morty is digging through is the one furthest to the left. Immediately after Tiny Rick shows up, Morty is suddenly standing behind the third locker from the left. But also, Tiny Rick originally appeared on the right side of Morty and has suddenly switched to Morty's left side in the following shot. (00:04:10)
Continuity mistake: This mistake occurs in four shots: As Summer asks Jerry for a ride to work, the small robot that Rick had built at the dining table has the butter to its left. In the second shot, the butter has moved to the robot's right side. In the third shot, the butter appears behind the robot. In the fourth shot, the butter returns to the robot's right. (00:00:50)
Continuity mistake: Whilst the family are eating breakfast, in the first shot of the breakfast table, Beth has a glass of orange juice in front of her plate. In the next shot, the glass is to the right of her plate. Two shots after, the glass is suddenly more forwards on the table. Jerry's glass and knife & fork also move.
