4x13 Death Is in the Air

Carlton Lassiter: [Lassiter, Donny, Shawn, Gus and Juliet are all being showered in the parking lot] I mean is this really necessary? I didn't even go inside the cafe.
Donny Leberman: Oh it's necessary. Yeah, the CDC doesn't want to take any chances.
Carlton Lassiter: For the last time, who the hell is this?
Donny Leberman: Oh, I'm Donny Leberman. Hey, I'm the guy who screwed all this up.
Carlton Lassiter: I'm not big on nude handshakes.
Juliet O'Hara: They're probably just being safe, Carlton. [Hit by a hose] Ooh, that tickles.
Carlton Lassiter: Spencer, are you shampooing your hair?
Shawn Spencer: Yes I am, Lassie. I always travel with a small packet of Johnson and Johnson's baby shampoo in my wallet.
Juliet O'Hara: Baby shampoo?
Shawn Spencer: No more tears, Jules.
Carlton Lassiter: [Getting scrubbed down] Whoa, take it easy, slugger, what are we dating?
Burton 'Gus' Guster: I can't believe this, Shawn. First, we're looking for a prostitute, now I'm naked in a parking lot.
Shawn Spencer: It's just like our prom night.
Burton 'Gus' Guster: Shawn.
Shawn Spencer: Gus, relax. Don't be Nick Cage's accent from "Con Air." We've bathed together before.
Burton 'Gus' Guster: When we were three.
Shawn Spencer: It's essentially the same thing. It's just impolite to pee. [to the person scrubbing him down] That feels great by the way.

Shawn Spencer: [Running up to a crime scene at a convenient store] Dude, we should come back later and hang out with our skateboards.
Burton 'Gus' Guster: You know that's right.

Shawn Spencer: Whoa, hey, hey, excuse me, uh, we just checked into this room, you think you could come back a little bit later?
Cleaning Lady: But it's not clean.
Shawn Spencer: That's okay, neither are we.
