Sheldon gets Leonard Nimoy's DNA as a Christmas present from Penny. Sheldon: "All I need is an ovum and I can make my own Leonard Nimoy!" Penny: "All I'm giving you is the napkin!" My favourite scene from the Big Bang Theory.
Vivien Leigh as Scarlett Ohara. I think this expression/scene was the ultimate Scarlett moment and really showed Vivien Leighs talent. In a second, she transformed from scared to THIS. Im a hot sexy bitch who doesnt care what you think.
