We’ve met Liz’s parents and Jack’s parents and Jenna’s mom and Frank’s mom but Kenneth’s family has been a mystery. And since they can’t get a pig to act, we are going to meet Kenneth’s mom and her special friend. Catherine O’Hara is in as Mrs. Parcell and Leaves of Grass superfan Bryan Cranston will be her companion. Both are classic perfect 30 Rock guest star castings and they reflect the final season’s raising of stakes. But if they really want to kick things up an emotional notch, O’Hara should bring with her Kenneth’s father-pig’s meatless carcass.
