It's a Big Bang Theory battle of the moms!
In one corner, armed with a Ph. D. in neuroscience, a strong belief in reward-based parenting, and multiple best-selling books -- it’s Dr. Beverly Hofstadter (Christine Baranski). In the other corner, armed with the Lord's protection, a strong belief in unconditional love, and her Texan right to bear arms -- it's Mary Cooper (Laurie Metcalf).
That’s right, ladies and gents! We can't believe it's taken us eight years to witness this highly anticipated face-off, but in tonight's all-new episode of the smash CBS comedy Leonard (Johnny Galecki) and Sheldon's (Jim Parsons) mothers are finally going to meet.
"It is as fun and as explosive as you might be hoping it is," Big Bang's executive producer Steven Molaro tells ETonline of Beverly and Mary's first meeting. "Both of them were just so wonderful to work with and it was a really fun episode to shoot."
Tensions are running high in tonight's half-hour when Mary and Beverly realize they could not be more opposite, which leads to an epic verbal throw down -- with Penny (Kaley Cuoco-Sweeting) literally caught in the middle!
"You're going to see all of it," Molaro teases. "You're going to see a very church-going, God-fearing woman who is not afraid to quote the bible, run head-first into a very science minded and sort of more cold, psychiatrist personality and the inevitable clash will occur."
Speaking of clashes, Penny and Beverly have had an emotional roller-coaster ride of a relationship over the years, and this will be the first time the two ladies will be together since Leonard popped the question.
"It is certainly touched on in the episode," Molaro said of Penny and Beverly's unique dynamic. "But then ultimately shifts over to focus more on Leonard and Sheldon."
Now that our Big Bang mothers are finally meeting, when are we going to get more scenes between the two most important women of Sheldon's life: his mom and Amy Farrah Fowler (Mayim Bialik)?
"Not this season, but we're well aware that that is a dynamic that needs to be explored further," Molaro answers. "There's only so much we can fit into one scene. We're certainly not done exploring Sheldon's mom and Amy, but there's only so much we could get done this year. That is certainly floating around in seasons nine or ten."
The Big Bang Theory airs Thursdays at 8 p.m. on CBS.
