Trivia: Creed says he transfers his debt to "William Charles Schneider" when he gets in trouble. Actor Creed Bratton was born William Charles Schneider. Schneider changed his name to Creed Bratton shortly after starting his music career, in the 60's, long before playing Creed Bratton in "The Office."
Trivia: When Michael is in Mr. Figaro's office, there's a flyer for Terry's Diner. This is a real diner located near Scranton (Moosic, PA) and the flyer has the diner's actual phone number (minus the 570 area code). It could also be a clue that Michael's 2nd job isn't in Scranton.
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.
