Trivia / The Office USS 9 E 4 Work Bus

• Troubled Production: The cast had to shoot on a real bus, which was uncomfortable. For actor comfort, the engine was kept running and a portable air-conditioning unit was hooked up. Unfortunately, the air-conditioning unit was placed next to the bus's tailpipe and pumped cooled engine exhaust back into the cabin, which went unnoticed for some time. Things could have gone badly, but, luckily, Jenna Fischer got a whiff of the exhaust and notified production so the situation could be remedied.
