30 Rock is getting ready to peel back another layer of beloved, effervescent redneck page-turned-janitor Kenneth Parcell (Jack McBrayer) in its final season. Get ready to meet his mom! And her "friend"!

"We're going to meet Kenneth's [family]," executive producer/star Tina Fey tells TV Guide. "Kenneth's mom will be played by Catherine O'Hara and his mom's 'friend' Ron will be Bryan Cranston."

It's unclear when and how the Breaking Bad Emmy winner and Best in Show scene stealer will show up, but with the two acting greats joining one of TV's best-written comedies, the potential is limitless.
