Katey Sagal is joining The Big Bang Theory

Katey Sagal has been cast as Penny’s mom, Susan,  in the upcoming season of The Big Bang Theory! And Jack McBrayer will be joining on as Penny’s brother, Randall.  These two along with Wyatt, Penny’s father, complete the family.

“We are finally going to meet more of Penny’s family,” executive producer Steve Molaro said. “We’re going to be meeting Penny’s mom and her brother in the first episode back. We’re super excited that Katey Sagal will be playing Penny’s mom.”

Susan is  “stressed out and neurotic from a life with her troubled son,” which makes sense given that Penny has referred to her brother in previous episodes as  “a cheerful former drug dealer and ex-con.”

Catch these two in action when BBT comes back Monday September 19 on CBS.
