This one's a certain classic from '93-- lyrics below if you want to sing along:
Lyle Lanley: Well, sir, there's nothing on earth Like a genuine, Bona fide, Electrified, Six-car Monorail! What'd I say?
Ned Flanders: Monorail!
Lyle Lanley: What's it called?
Lyle Lanley: That's right! Monorail! [crowd chants `Monorail' softly and rhythmically]
Miss Hoover: I hear those things are awfully loud...
Lyle Lanley: It glides as softly as a cloud.
Apu: Is there a chance the track could bend?
Lyle Lanley: Not on your life, my Hindu friend.
Barney: What about us brain-dead slobs?
Lyle Lanley: You'll be given cushy jobs.
Abe: Were you sent here by the devil?
Lyle Lanley: No, good sir, I'm on the level.
Wiggum: The ring came off my pudding can.
Lyle Lanley: Take my pen knife, my good man.
I swear it's Springfield's only choice... Throw up your hands and raise your voice!
All: Monorail! Lyle Lanley: What's it called? All: Monorail!
Lyle Lanley: Once again... All: Monorail!
Marge: But Main Street's still all cracked and broken...
Bart: Sorry, Mom, the mob has spoken!
All: Monorail! Monorail! Monorail! [big finish] Monorail!
Homer: Mono... D'oh!
