Catherine O’Hara Joins ’30 Rock’: Greatest. News. Ever.

Tina Fey has become the poster child for female writers and comedians since her time as head writer on Saturday Night Live, and now the genius behind Liz Lemon is adding SCTV alum Catherine O’Hara to the 30 Rock cast for the show’s final season. Hurrah!

O’Hara will be playing the mother of Kenneth (Jack McBrayer) for an indeterminate number of episodes this season. Given 30 Rock‘s ability to utilize their guest actors to the fullest of their abilities, and O’Hara’s ridiculous comedic talents, we feel pretty safe in saying this Canuck is walking home with the Best Performance by an Actress in a Guest Role in a Comedy Series Emmy next year.

Sorry Jean Smart.
