Happy Birthday, Surprise! This week's episode is chock full of goodies. We have the birthday party, the Jim and Dwight alliance, and the introduction to the notorious PPC (Party Planning Committee). Angela has a realization about Dwight's bobblehead collection, and both ladies catch a few continuity errors. Finally, Jenna and Angela call up Phil Shea, Prop Master of The Office, to answer the big questions about that box!
