Laurie Metcalf (Mary Cooper)
They say the apple doesn’t fall far from the tree, but anyone who watches TBBT knows that this doesn’t apply to Sheldon Cooper. Mary Cooper, his loving mother, has had to deal with a lot when it came to raising her genius son.
The two don’t share very much in common. For starters, Mary is a born-again Christian woman who has the faintest idea of what her son does for a living. Despite their differences, she loves him with all her heart, and has even come to Leonard’s rescue on more than one occasion when it came to handling her genius son that we all know and love.
