I like to think of this in the literal sense. That Nathan is actually the Twitter server, lol. :0)

Sarah, did u see Nathan's photo with the snake? I'm wondering if it's a real snake.

Hahaha! From Nathan's Tweet: "If someone says, "…that's what she said." I respond, "…to her friend, who was also a slut."

Two recent note-worthy tweets from NF: 

Inception. All I'm gonna say is: Hotel hallway. That's a long way from 3rd Rock from the Sun. Nice.

And previously: 

In LA, you have to know where the cool places are. In NY, everywhere you go is cool.

To which I would add, true up to a point. In the right neighborhood, everything is cool in L.A., too. (I'm looking at you, Larchmont Village, best kept secret middle class celebrity hangout — and next door to Raleigh Studios, to boot) 

NF is the reason I got on twitter. He is hilarious, and cryptic, and sometimes lewd. But he is always real and I like that. He only pimps charity stuff which is cool too.

His best tweet of all time is: "How many diffrnt countries is Castle playing in, and where is it the most

popular? I'm planning a vaca and don't want to wait in any lines."

That is NF in a nutshell, he is a smarta**, but self-deprecating enough that you still love him, and he can get away with stuff like that.
