After Beaver has returned home and eaten the sandwiches, he answers the phone on Wards desk and talks with Wally. The phone cord keeps switching positions when he is on the phone.
After Beaver gets in the car to go back to Crystal Falls Wally hands him his suit case and says you don't want to forget this. Wally would have picked up the suitcase at the Crystal Falls bus station and it would have already been in the car.
Beaver asks a man at the bus station which bus is his, and is told bus 12. But the 2 that shows is an upside down 5.
