When George (Jason Alexander) and Jerry (Jerry Seinfeld) are at the tennis match, crowd applause is heard after a player scores, but in the following shot, no spectators are clapping.
When George is trying to get Jerry's attention at the tennis match as Jerry is transfixed by the lineswoman, he has his hinged-sunglasses shades up; in the cutaway they are down.
When Jerry is trying to chat up the lineswoman after the match, an extra in a green-and-white striped T-shirt passes behind him twice.
Kramer (Michael Richards) plays ballboy at the end of the episode and can be seen sitting next to the net. The following scene is a long shot and shows the whole court. Kramer was not where he was sitting in the previous shot.
Laura's (Marlee Matlin) hands are in the air following Kramer (Michael Richards) running into Monica Seles (Monica Seles). In the next, close-up shot of the scene, her hands are on her head.
Jerry (Jerry Seinfeld) can be seen laughing when Newman (Wayne Knight) says, "When you control the mail, you control information."
This episode begins on a Friday; the next scene is a Saturday with George (Jason Alexander), Jerry (Jerry Seinfeld), and Laura (Marlee Matlin) being at the restaurant. The following scene is Todd's (Jerry Sroka) party, which was supposed to be on a Friday.
At the party, when Laura is reading lips and signing to Kramer so he can translate, the implication is that Kramer is screwing it up. But, unless the ASL signs for "sleep" and "sweep" are very similar (so that Kramer is making a mistake in reading the sign), Laura is actually the one making a mistake in reading lips, and thus is making the sign for "sleep" instead of "sweep," and Kramer is correctly interpreting her signs.
George (Jason Alexander) asks Laura (Marlee Matlin) how she knows a couple is breaking up, as if he is unaware she can read lips, but moments earlier he was speaking to her about a lack of napkins and she was reading his lips.
