In his book "The Bassoon King," Rainn Wilson said that his favorite exchange from his entire time as Dwight Schrute came in the episode "The Alliance" when Dwight offered Jim the titular deal and Jim immediately and enthusiastically accepted it.
When the employees are singing "Happy Birthday" to Meredith, a red-haired employee can be seen in the background singing with them. She is never named or seen again.
This is the first instance of Jim stating "Absolutely I do" when asked to do something by Dwight, something he later tells Pam to do.
Prop master Phil Shea doubled for Rainn Wilson in the scenes where Dwight is hiding in the box in the warehouse but not seen (as revealed on the Office Ladies Podcast).
If Jim ended up donating $50 at $3 per mile, Oscar's nephew would have to reach 16.67 miles. Which means Michael, donating $25 per mile, would end up having to pay $416.75.
