Seinfeld

Goof: In the scene where Kramer carries the pop cans down the hall toward his apartment and trips, all of cans spill out of the boxes. When the camera cuts to the next shot and Kramer is the floor, one of the boxes is upright with all of the cans inside.

The bakery where they buy the rye is repeatedly referred to as "Shnitzer's". As the interior of the bakery, as well as the woman who works there are the same as in the bakery from Season 5's "The Dinner Party," we are led to believe that this is the same bakery. However, in that episode, the exterior of the bakery is shown, and the sign outside reads "Royal Bakery."

On a DVD commentary, Jerry said this was his favorite episode.

When Jerry throws the Rye for the last time before trying the fishing rod, it's clear that the rye will touch the ground. As such, it's odd that the rye is unharmed, and that Jerry is willing to handle it.

When Jerry is trying to throw the rye up to George, Susan is not home yet. George mentions to Jerry that Susan won't be home until 8 o'clock for dinner. However, when George finally gets the rye into the house, Susan and her parents are all standing there shocked. How did Susan get in the house? Wouldn't Jerry and Kramer have seen Susan walking into the apartment? No mention in the episode of another entrance.

When Jerry goes to pick up the rye, the old lady asks for a marble rye "in a plastic bag" just like the one that Mr. Costanza stole. When Jerry steals the rye it, presumably with the plastic bag on it as well, is inside a paper bag. When Jerry walks up to the Ross' house, he's carrying just the rye, no bag or bags. Wouldn't George want the rye in the plastic bag? Why would Jerry throws the bags out to begin with? To destroy evidence? The old lady asked for the rye not to be put in a plastic bag. Although ironically, the Costanza's rye was in a plastic bag.

When George and the Rosses are standing outside the Rosses apartment it appears that they live in a brownstone. Later on, when Jerry is throwing the Rye to George in the window we see the people who live in the apartment below looking at the Rye outside their window. This implies that the Rosses live on the top floor of the brownstone. This isn't a huge goof but people who have as much money as they do do not live in one floor of a brownstone, they own the whole thing.

Frank Costanza was somehow able to take back the marble rye undetected. Yet a few scenes later George explains that the Snitzer marble rye is too big to sneak in under a coat.

George is Jewish. They reference this fact when he attempts to convert from Judaism to the Eastern Orthodox faith. Also the template for George, Larry David, is Jewish. In "The Conversion," nobody ever states that George is converting from Judaism. He's simply converting from whatever religion he is, which could be Judaism, to Latvian Orthodox. It's unclear what religion George was before converting.

The lady at the deli picks up a marble rye off of the shelf, hands it to Mable and says "it's the last one". But, there are clearly 5 or 6 more loaves left on the shelf.
