Big Bang Theory Quote
Sheldon: Not only is it signed to me, but this is where he wiped his mouth. So we are currently in the presence of Leonard Nimoy's DNA
Wil Wheaton: Um, doesn't Adam count s Leonard Nimoy's DNA?
Sheldon: No offense, but this is pure 100% Nimoy, and because of your mother, you're only 50%. Which isn't bad, but anything that you wipe your mouth on gets thrown away.
