*Police Radio*: It was literally giving a hummer to a hummer.
Will Ferrell: You find anything?
Police Investigator: Yeah, we found a lot of stuff. Bodily fluid and hair samples, we determine a bunch of old homeless dudes had an orgy in the car.
Will Ferrell: Oh god.
Police Investigator: Yeah, you know what's that called when they do that in there? It's called a Soup Kitchen. It's a pretty rough stuff. Not long after that, a mama raccoon came along and *sniff* gave birth on the floor. Found a deer vagina.
Will Ferrell: Awww, what?!
Police Investigator: That could've just been there from before though. We thought it was human lips at first. I've never seen so many fluids.
