The episode starts with Arthur in his bedroom in bed looking a little bit frighted.
Arthur sits up in his bed.
Arthur: Have you ever have something really embarrassing happen to you?
Arthur: Once, I was in a school play and I forgot my lines
The camera goes to Buster.
Buster: And don't forget me
Arthur: Then there was a time I told everyone I could play the Rachmaninov prelude in C sharp minor blindfolded… and Miss Krasny asked me to do it. Arthur sits in music class. What, no blindfold? Sorry, can't do it.
Arthur: I'm sorry I'm late, Mr. Ratburn! I guess my mom just forgot to wake me up and—
(the other students laugh)
Nigel Ratburn: Mr. Read, being late is one thing, but not wearing any trousers - that is quite another.
(Arthur wakes up screaming. It was just a nightmare!)
Arthur Read: What a horrible dream!
In the laundry. Buster has hypnotized Arthur. He then seemingly wakes Arthur up.
Buster: Arthur, wake up, you were asleep. Did you have the dream?
Arthur: No, I don’t think so.
Buster: Hh. Then it worked, just like on TV. He snaps his fingers.
Arthur: Wow, you cured me, Buster! I'm cured. Whoopee! His pants slip of. Hey, how did I do that? His pants get up and grow teeth.
Buster: Maybe your mom’s been using too much starch. Arthur’s pants chase Arthur.
Arthur: Hh! Help!
Buster: Yep! Those pants sure need a lot of fabric softener.
Arthur is in fact still asleep in the laundry.
Arthur: Get them away! They're trying to eat me!
Buster: Arthur, snap out of it. You are now… snaps ...awake.
Arthur: Great. Now I’m not afraid of losing my pants. I’m afraid of being eaten by them. Promise you’ll never tell anyone about this.
Buster: Your secret is safe with me, Arthur. Cross my heart and hope to die.
In the school cafeteria everybody seems to know about Arthur’s dream.
Arthur: Buster! Buster! Wake me up, I'm having a nightmare!
Buster: You don’t look like you’re asleep. Why do you think that?
Arthur: Because everyone seems to know about my underwear dream.
Buster: Not everyone. I just told a few kids.
Buster: Ohhh! Here we go again.
