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.
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.
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!
A wedding ceremony with all of their friends and family surrounding them is everything we've wanted for a few seasons now. It's emotional for everyone involved.
This photo might be the cutest thing ever. Even better is that it features guest stars Jack McBrayer, Katey Sagal, and Keith Carradine as Penny's brother, mother, and father.
They did it! Leonard and Penny have had quite the journey, so it's even more exciting to see them celebrate their marriage with everyone they love. This wedding photo? Priceless.
Oh man, Penny doesn't look happy with her mother-in-law at all. This is going to be an awkward wedding, but mostly that's thanks to Leonard's dad and Sheldon's mom...
Sheldon: I'll have a diet Coke. Penny: Can you please order a cocktail? I need to practice mixing drinks. Sheldon: Fine... I'll have a virgin Cuba Libre. Penny: That's... rum and Coke without the rum. Sheldon: Yes, and would you make it diet?
