STU: I don't know, man. It just hit me. You remember when we saw Doug's mattress impaled on that statue? - Yeah, we threw it out the window. - No, impossible. - You can't open windows in Vegas hotels. - Well, then how did it get...? - Oh, my God! - Ha, ha, ha. - Whoa, wait. What's going on? - Doug was trying to signal someone. - Holy shit. STU: Yes. - Wait. How did you figure that out? - Doug made me realize it. - Doug? - Uh, not our Doug. Black Doug. - Hey, hey, easy with that shit. Come on. - Sorry. Can someone tell me where white Doug is? - He's on the roof, Alan. - Yes. He's on the roof. We must have taken him up there as a prank... ...so he'd wake up on the roof. - Like that time in summer camp. We moved his sleeping bag out in the jetty at the lake? Ha, ha, ha. Which was hilarious. It's not so funny now, though, because we forgot where we put him. You guys are retarded, you know that? - Holy shit. You think he's still up there? - There's only one way to find out. PHIL: Doug! Doug! - Doug! PHIL: Doug, you up here, buddy? Where you at, Doug? Doug!
