Tonight on 30 Rock, we get another big name guest star to attract even more viewers even though it is a one time thing. Scratch that, tonight on 30 Rock we get Mad Men star Jon Hamm to star a multiple episode arc as a love interest for our favorite girl Liz Lemon (Tina Fey). Jon plays Liz’s new neighbor who she is very smitten by and eventually turns suitor. This should be a fun episode. As always, after a brand new The Office, 30 Rock starts at 9:30/8:30c.
