At the Circus Burger, a woman in a purple suit mysteriously appears then disappears behind Craig when he places his order.
Three Krelboynes test Barton on Chaucer. During the quote, Barton rests his face on his right hand (change camera) then on his left hand.
Richie shows Reese around the Circus Burger. We see Richie pick up a slice of cheese, take a bite from it but in following shots, it has inexplicably vanished from his hand.
Mr. Herkabe walks across the classroom extolling his latest protege. He has a book in his hands. In one shot, the spine is in his left hand then in another in his right hand.
Barton bids farewell to Mr. Herkabe. Herkabe holds a pen/pencil wrapped in his fist, then between camera shots it's between his fingers.
Francis approaches Pete to talk to him about his "big day" with a Russian Mail-Order Bride. The scene opens with a small joke about the mirror that Pete is looking in when Francis enters the room. Ironically, throughout the rest of the scene you can see the camera and crew in plain unobstructed view in the mirror. You can even see crew standing behind it. The camera at one point even dollies forward making it even more visible in the mirror.
As Reese rings up Craig's order, the running total on the cash register never changes from $0.00, and the final total remains $0,00 even as he is telling Craig the final cost of his meal.
