- Disguise.

- Kind of, I guess.

- It's a hell of a job.

- That's cool, man.

- Like a day-to-day basis, it's fine.

- Like today, I, like, sat in my car I smoked, like, 10 doobies, and then I went to go visit my girlfriend at lunch.

- Nice.

- What? You sucked on her titties?

- No, I just kissed her. I just did that to make it seem cool.

- That's cool. Does she like to smoke weed?

- A little sometimes. She has a couple... She's in high school, so as much as any high-school kid.

- She's cool as hell, actually. You'd get along with her I guess.

- Yeah, you know, it only sucks when I go visit her in high school...

- And all the guys she goes to school with are strong and handsome and really like funny. Like, do good impressions of Jeff Goldblum and shit like that.
