Sheldon Cooper is quite a character, but how exactly did he grow up to be the nerdy and abrasive yet still lovable guy he is today on The Big Bang Theory?

The new spin-off series Young Sheldon tells the story of Sheldon’s life growing up in small town Texas as the brainiac oddball in his sports-loving family.

CBS has released a first look at the show, which stars Iain Armitage (Big Little Lies) as young Sheldon.
