Big Bang Theory Quote
Penny: Who's Amy?
Leonard: His girlfriend.
Penny: (blindsided by the news) Sheldon has a girlfriend?
Sheldon: She's not my girlfriend.
Penny: How long has this been going on?
Leonard: Four months.
Sheldon: She's not my girlfriend.
Penny: Are you telling me for the past four months, I have been asking you "What's new?" and you never thought to go with "Sheldon has a girlfriend"?
