We can obviously expect a lot of family drama when the parents come to visit, but it sure looks like Leonard's dad and Sheldon's mom are hitting it off... yikes!
When does she ever? Christine Baranski returns as Leonard's mother, Beverly. We love it every time she makes a guest appearance, and this particular time is going to be fantastic.
In nine seasons of The Big Bang Theory, we've never met Leonard's father. Until now! Chaos ensues when he shows up, along with both Leonard's other and Sheldon's.
Of course, Sheldon is also bound to have some opinions about all of this. But how much will all the chaos affect whether or not Penny and Leonard actually get their ceremony do-over?
After talking with Leonard's mother, Penny has decided to try planning a wedding ceremony that their friends and family (and the audience) can be a part of.
Howard has to be proud of the navigational system he and the guys have been working on together. But is the government really out to get them because of it?
Sheldon's mother (Laurie Metcalf) also visits for the special occasion, as Penny tries to plan a wedding ceremony that will include all of their family and friends.
