From an article posted on The Hollywood Reporter:
I laugh less at Sorkin's witty banter than I do at the thought that viewers in Peoria are futilely looking up jargon in the dictionary such as "upfront" and "demo" in an attempt to understand the dialogue.
Sigh. My parents live in Peoria, and I can assure you they know what an 'upfront' and a 'demo' is. Sheesh, what arrogance.
