Plot hole: When Jim's bank calls his office, Kevin is there and ends up pretending to be Jim. The Banker automatically assumes that he is not in Puerto Rico only from asking his address and social security number. It would have been very plausible for him to have forwarded the number to his cell phone, where the same scenario could conceivably occur (since The Banker refused to listen when Kevin tried to correct her).

Michael Scott: This is an environment of welcoming, and you should just get the hell outta here.

Suggested correction: Michael didn't establish the contract with Hammer-mill. Rather, he locked them up as an exclusive supplier. It's unknown if they were already selling the products to Dunder Mifflin alongside Staples and Office Max.
Wrong, Josh says they cannot sell Hammer-mill products as they are exclusive to Staples so therefore they wouldn't have been able to sell there products alongside as mentioned before until Michael made them an exclusive to them solely, Dunder Mifflin. Therefore the original mistake stands true.
