Glee Quotes

I had sex with you because you got me drunk on wine coolers and I felt fat that day. But it was a mistake.

Quinn [to Puck]

[to Rachel] You and I both know how this thing ends. I don't know how, or when, and I don't care where you're living or what dope you're shacked up with. You're my girlfriend. We are endgame. I know that and you know that.
