Tina Fey To Guest On “The Simpsons”

Liz Lemon is coming to Springfield! Well, not exactly...

"30 Rock"'s Tina Fey will make a guest appearance on "The Simpsons" this coming season playing Ms. Cantwell, a substitute teacher who play favorites when it comes to Lisa Simpson.

“She gives Lisa a ‘B’ and Ralph an ‘A’ even though Ralph signed his paper ‘Ralpa,’” executive producer Al Jean tells Entertainment Weekly.  “And Lisa has a reading kangaroo with a bunch of little joeys in it for the books that she reads, and [Ms. Cantwell takes the joeys out and puts them in other kangaroos. Hardcore stuff.”

BTW, the final season of "30 Rock" kicks off Oct. 4 on NBC.
