[Act 1]
Bart: Watch this ugly face.
Lisa: That's nothing! Check THIS out!
Maggie: [speaks gibberish]
Bart: That's nothing, man! Check this...
Marge: Are you kids making ugly faces?!
Bart: Maybe?
Marge: Well you know, if you keep making those faces, you'll freeze that way, and be stuck with a HORRIBLE face forever!
Lisa: You think Mom is telling the truth?
Bart: Mom wouldn't lie
Both: ALRIGHT!
[Act 2]
Bart: Watch THIS scary face!
Lisa: Oh, yeah?! That's NOT scary!
Bart: Oh, yeah? That's not scary!
Lisa; Oh, yeah? THAT'S NOT...
[Marge suddenly appears and makes a scary face]
Both: [scream in horror] SCARY!!
[Act 3]
Lisa: I call this face "The Howller Monkey" [makes one]
Bart: I call this face "Dad" [makes a caricature of Homer Simpson, then suddenly...]
Marge: Alright, I told you, If you kept making those HORRIBLE facеs, they'd FREEZE THAT WAY! AND NOW THEY HAVE!
Lisa: They have?!
Bart: Our facеs are frozen?!
Marge: YES THEY ARE! Look at the mirror and see for yourselfs.
[They all look in the mirror and scream in terror]
All 3: WE'RE DOOMED!!
