The clip begins with Sheldon Cooper (played by Jim Parsons) and Amy Farrah Fowler (Mayim Bialik) arrive back from the awards ceremony.
Sheldon began: “We did it.”
To which a teary-eyed Amy responded: “I know, can you believe it?”
Turning to Leonard, Sheldon added: “That’s a good point, what if I’m dreaming?”
To which Leonard quickly slaps Sheldon across the face, before a black and white montage of the actors receiving past awards appeared on screen.
The Big Bang Theory season 12 is available on CBS and All4.
