We spotted Tina Fey and Alec Baldwin hard at work yesterday filming scenes on location for the upcoming season of 30 Rock!  It's so refreshing in an age of reality programming consisting of strippers competing in egg and spoon races to win cell phones and "love" to see an actual sitcom that's both hilarious and smart.  I'm just as excited this fall to see Liz Lemon do battle with the likes of Jack Donaghy and Tracy Jordan as am I Blair Waldorf with Chuck Bass. 

Click through the gallery to see Tina and Alec do their thing, then watch the clip below that someone compiled of all of Liz Lemon's best quotes from the show, it will having you loling in your cubicle.
