"The Reason You Suck" Speech: Maria really rips Oscar a new one when Big Bird goes missing:
Maria: Oscar, I hope you're satisfied, you had to start all that stuff about Santa and tiny chimneys, and you've upset Big Bird so much, he's gone.
Oscar: W-well, I didn't know he'd do anything dumb like that, I was only teasin' him.
Maria: Teasing him? Telling him that Santa's not going to bring anybody any presents because he can't get down a tiny chimney, now you call that teasing?!
Oscar: Well, uh, he'll come back, he's part homing pigeon! Besides, what's the big deal? He lives outdoors all the time, anyway!
Maria: Now look here, Oscar... the nest is something different, that's his home, he's got an electric blanket, he's got heating pads, and he's around all the people that he loves. But here it is Christmas Eve, and he's out there somewhere in this big city, and it keeps snowing, and it's getting colder, *On the verge of tears* and he could be in serious trouble unless we find him! So what are you going to do about it?!
Oscar: Well, I'm gonna find him, and bring him back! Get me off'a here!
