Big Bang Theory Quote
Leonard: Not once did my mother ever give me any love or affection for just being myself. I always had to earn it.
Mary Cooper: Oh, Leonard, I'm sure she loves you very much. In her own cold godless way.
Penny: Yeah, and you certainly don't have to earn my love.
Leonard: Thank you.
Penny: Of course you already knew that when you bought me this princess-cut drill bit.
