Big Bang Theory Quote
Leonard: So, mother, surprised you came all this way for Sheldon's birthday.
Dr. Beverly Hofstadter: Oh, I was happy to; he did come to my sixtieth.
Leonard: Oh, you had a party for your sixtieth?
Penny: I wouldn't call it a party. Just a few close friends. And your sister and brother.
Penny: Yeah, to be fair, we did get married in Vegas and didn't invite her.
Dr. Beverly Hofstadter: And I never did thank you for that, dear.
