Rex: I used to sleep on a lamb's wool beanbag next to an electric space heater. That's my territory, I'm an *indoor* dog. King: I starred in twenty-two consecutive Doggy Chow commercials. Look at me now, I couldn't land an audition. Boss: I was the lead mascot for an undefeated high school baseball team. [sneezes] Boss: I lost all my spirit, I'm depressing. Duke: I only ask for what I've always had, a balanced diet, regular grooming, and a general physical once a year. Rex: I think I might give up. Duke: What, right now? Rex: Right now. [turns around] Rex: There's no future on Trash Island. Duke: [sneezes, then turns to Boss and King] You heard the rumor, right? About Buster? [All the four dogs murmur] Boss: Who's Buster? Duke: Uh, my brother from another litter. King: What happened to him? Duke: Suicide. Hanged himself by his own leash. Boss: Aw, boy... Rex: I want my master. Chief: [scoffs in disgust] You make me sick. [vomits off to the side and walks up to the four dogs] Chief: I've seen cats with more balls than you dogs. [shouts at Duke] Chief: STOP LICKING YOUR WOUNDS! [Duke looks around awkwardly with his tongue out. Chief walks up to Boss] Chief: You hungry? Kill something and eat it. [walks up to Duke] Chief: You sick? Take a long nap. [walks up to King] Chief: You cold? Dig a hole in the ground, crawl into it, and bury yourself. [walks up to Rex] Chief: But nobody's giving up around here, and don't you forget it, ever. You're Rex. You're King. You're Duke! You're Boss! I'm Chief. We're a pack of scary indestructible alpha dogs. You're talking like a bunch of housebroken... pets. Rex: You don't understand. Uh, how could you, I mean you're a... Chief: Go ahead say it. I'm a stray, yeah.
