When Kramer (Michael Richards) comes home late from work, Jerry (Jerry Seinfeld) has a bandage on, but in the following scene it is missing.
Elaine's purse is thrown onto the chair that Kevin (Tim DeKay) sits in after Elaine (Julia Louis-Dreyfus) pushes him down. However, when he sits in it, the bag is gone.
George's (Jason Alexander) photo of Gillian (Kristin Bauer) had writing on the back. However, when he gives it to Nikki, the back is completely blank.
Elaine (Julia Louis-Dreyfus) picks her bag up from the floor as she leaves Kevin's (Tim DeKay) apartment. Yet earlier, when she arrived, she had placed it on the chair.
Several times in the episode, like when she is going to wash her hands, Kristin Bauer's (Gillian) real, smaller and more feminine hands are visible.
As Kevin shows the ballet tickets to Elaine, he looks at his fall zone behind the couch to make sure he's lined up.
Near the end, Jerry and George go to the nightclub, only to find it turned back into a meat packing warehouse with many sides of beef hanging from the ceiling. In such a cold environment, Jerry and George's breath should be visible, but isn't.
A flame is visible at the bottom of the screen when George (Jason Alexander) puts the hairdryer on the picture of Gillian (Kristin Bauer).
In this episode, Kramer is making breakfast in Jerry's apartment and as Jerry comes out of his bedroom, a boom mic is visible high above his head.
Near the end of the show, when Kevin opens his apartment door to let Elaine in, the shadow of the boom mic can be seen moving at the top of the doorway before she walks in.
