Amy notes that Meemaw is sitting in Sheldon’s spot (something that Sheldon says he’ll never let Amy do) before Sheldon leaves the two alone to get the guest room ready.

But things get a little problematic when MeeMaw makes it clear that she’s there to size Amy up and so far she’s not that happy.

A third clip shows Raj (Kunal Nayyar) second guessing his relationship with Emily (Laura Spencer) after meeting an intriguing woman named Claire, played by guest star Alessandra Torresani.

The 87-year-old actor, best known for portraying the superhero Batman and his alter ego Bruce Wayne in the campy 1960s television series (as well as the original 1966 film) has been the subject of discussion on many an episode of The Big Bang Theory. He will be playing himself in the series.

Details surrounding the plot of the episode are being kept quiet.

West is joining a roster of the show’s special guest stars, including Bob Newhart, Stan Lee, George Takei, Katee Sackhoff, Leonard Nimoy, Stephen Hawking and Summer Glau.

At first, Sheldon thought that his grandmother missed him so she made a decision to visit him.

The 200th episode of The Big Bang Theory will air in the USA on 25 February (16).
