On the phone with the cable company, Ray gives his address as "320 Fowler." In earlier episodes, the number "135" can be seen on the door.
When the cable seems to be coming back, the lid for the game and the plastic cardholder are sitting at angles to each other on the table. After Ray sits down and the game resumes, both objects are at different angles without being touched.
After Robert throws the rule book into the box lid, it changes position between shots without being touched.
When Frank and Marie come in from the rain, the wet stains on Frank's jacket, particularly his left shoulder, change between shots.
After Ray receives the ticket for pirating cable, the way he holds it changes between shots.
When Frank is on the phone with the cable company, he threatens to withhold money off his bill for the service interruption. However, if he had been getting Ray's cable from an illegal splitter, he wouldn't be getting a bill. (Of course he could be referring to Ray's bill on the phone).
