The Daria Episode Guide:
Sealed With a Kick

Daria borrows a pencil from Kevin, so he thinks she likes him, and gives her the "brush-off." Daria gets annoyed, and decides to get some revenge.
She starts being very friendly to him, especially when Brittany is around. When Brittany finally breaks up with Kevin, Daria has totally confused Kevin. He comes over to her house to ask her out, and while she starts to brush him off, he notices Quinn, and the two of them immediately hook up. It ends with Kevin and Quinn parked in the middle of nowhere, and Quinn's beeper going off.

I didn't notice any particularly great lines on my first viewing. I'll watch it again sometime.
