Allison Williams plays Marnie on HBO's 'Girls'. (Kyle Blair/WENN.com)

Allison Williams, I promise you I'm not this shallow or superficial.

But in a joking way, I had the following thought when I knew I was going to be interviewing you.

Okay, so you're one of the main cast members on the acclaimed series Girls. You're funny. Obviously you're very nice-looking. You're dad is famous newscaster Brian Williams, so you come from a high-achieving, well-to-do family. And you've graduated from Yale, so clearly you're super-smart.

So, if I were a 24- or 25-year-old guy, what in God's name could I possibly say or do to impress you?

Allison Williams laughed very hard at that.

"Everything impresses me!" she said.
