Tina Fey To Voice Teacher On 'The Simpsons' And More Casting News

Liz Lemon is causing some trouble for Lisa Simpson.

According to EW
, Tina Fey is headed to the animated Fox series as the voice of Ms. Cantwell, a substitute teacher who comes down pretty hard on Lisa.

“She gives Lisa a ‘B’ and Ralph an ‘A’ even though Ralph signed his paper ‘Ralpa,’” executive producer Al Jean told EW. “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.”

Additionally, Fey is getting ready for the final season of "30 Rock," which kicks off on Thurs., Oct. 4 at 8 p.m. ET, and will feature a cameo by the one and only Ryan Lochte.
