I like Moe so I enjoy the episodes based around him - and enjoyed the nod to other Moe's Bar makeovers. Did we always know Chalmers' first name was Gary?
30 Rock is on fire right now. Not only did we get an AWESOME homage to Harry and the Hendersons, but we got this gem of a line: "I actually wanted breakfast in bed with Robocop while an elephant painted our picture." More, please.
