While Jerry (Jerry Seinfeld) waits for the elevator, he talks to the doorman (Larry Miller) who is standing behind holding the newspaper in both hands. He lowers the paper & changes expressions during the conversation, but when Jerry turns back to the elevator, we see the doorman back in his original pose. An editing problem.
George (Jason Alexander) said he saw his father naked in The Statue (1991), so he shouldn't be surprised he has breasts. Response: George never said at what age he saw his father naked. He could have seen his father naked 20 or more years earlier when he didn't have breasts.
