Mark and Lexie in “Valentine's Day Massacre”

Mark

It must suck to work on Valentine's Day. I don't believe we've met... [Lexie turns around and looks at him] Ahhh! What'd you do to your hair?

Lexie

I changed it. I.. I colored it. I just... [sighs] Wait, you thought I was someone else. You didn't know it was me, and you were hitting on me?

Mark

No, no... I pretty much thought that you were some blonde.

Lexie

You are pathetic. And hypocritical. And slutty.

Mark

And you are no blonde. You can't pull that off. Blondes are either bad-ass or fun. And you're... you're a brunette.
