After Bonnie's male room mate moves out, George arrives at the apartment with the re-gifted label maker. He realizes that all the furniture, etc. belonged to the room mate, and rants about the absence of the velvet couch. Before the rant he wasn't holding anything, but the next camera cut shows him holding a portable TV, as if he had been holding it the whole time. The portable TV, it turns out, belonged to the room mate, and was "lost in the mail" (because all of the room mate's possessions had been boxed and labeled with the label maker's faulty adhesive). Newman shows up with the portable TV at the super bowl (presumably after harvesting it from the Postal System's "lost" and found).
There's a pipe next to Jerry's apartment door, presumably for water and made of a strong metal. When Newman squeezes through the door against Jerry's attempts to keep him out, he knocks against this pipe a couple times and the pipe easily bends each time.
Glue droplets can be seen on Scott's (Cleto Augusto) boxes when the labels fall off, but the label maker labels have an adhesive backing - glue wouldn't be used.
As Jerry is walking to his seat at the Super Bowl he says out loud that his ticket reads seat four, but when he gets to his row Newman is in seat four and Jerry sits in number three.
