The Big Bang Theory Season 5 Quotes

Bernadette: I've actually been thinking I'm going to hyphenate: Bernadette Maryann Rostenkowski-Wolowitz.
Penny: Nice. You know, you should totally get Bernadette Maryann Rostenkowksi-Wolowitz.com before someone snaps it up.
Bernadette: Howard already took are of it. Plus he set up our beautiful wedding website with cute little facts about our family histories. Do you know for a while, in Poland, my family and his family were neighbors.
Penny: Aww, that's cool.
Amy: No, it's not. I'll explain it to you later.

You can't ruin a friendship with sex that's like trying to ruin ice cream with chocolate sprinkles.

Raj
