The cutaway of Jenna achieving new heights (?) of 'sexy' baby-talk is such a great example of 30 Rock's excellence. Obviously just the idea/'line' is funny, but the execution (her hilarious acting- I still think JK is terribly underrated,- but also Tina Fey's sidelong weary glance, the timing of the cut to and back, the guys' evident fascination) and depth of detail (what Jenna, Liz and the guys are wearing, Liz's hair) -- take it to a new plane. Such loving attention to probably not even 3 seconds of screentime. I love that.
