Glee Quotes

[to Kurt] You know, these Mounds bars are delicious, but you have to eat them. If you just hold them in your hand hoping that you might get to eat them one day, they're going to melt and you'll look like somebody just pooped in your hand. Don't let waiting for things to maybe work out with Blaine turn you into the guy who looks like somebody just pooped in their hand.

Brittany

Blaine: Where's the bed?
Brittany: I removed it because when I imagined you two having sex I imagined a U-haul mounting a moped.
