After nine years of hearing stories about Sheldon's beloved grandmother, we finally got to put a face to the name. Sassy and strong-willed like her daughter, Mary, Sheldon's grandmother Constance, better known as Meemaw, was a real hoot who shook things up in Sheldon and Amy's relationship.
On a mission to determine if Amy was good enough to be with Sheldon, Meemaw made sure to point out every flaw she could find—and managed to spill the beans about Sheldon's engagement ring!
