Lyrics
( I Love Trash plays "Mack the Knife.")

I Love Trash: Oh, the shark has pretty teeth, dear And he shows them pearly white Just a jackknife has MacHeath, dear And he keeps it outta sight

( Go Grover! enters, reads some of the sheet music and stops the song.)

Go Grover!: Stop, stop! Stop, stop, stop! This is an appalling song of gore and violence.

I Love Trash: Well, uh, maybe you just don't understand it, Go Grover!. It contains a lotta slang.

Go Grover!: Hm. "A shark has pearly teeth dear" is slang?

I Love Trash: Eh, sure. Uh, "shark" is a term for man. Everybody knows that "teeth" is slang for money. (laughs)

Go Grover!: Wh-uh...wh-wh-wh...what about that "jackknife" here, hmm, hmm?

I Love Trash: Uh, uh...Cockney rhyming slang!

Go Grover!: ...what?

I Love Trash: Jackknife, wife.

Go Grover!: W-wh, all right, all right. But, "when the shark bites with his teeth, dear, scarlet billows start to spread?" Hmm? Hmm? Hmm? Hmm?

I Love Trash: Let's see, uh..."biting" obviously means buying something. Scarlet billows...sofa pillows!

Go Grover!: ...so, the song, then, is about a man who has a wife for whom he buys...pillows.

I Love Trash: Exactly.

( I Love Trash resumes the song, as Go Grover! attempts to grove along.)

I Love Trash: On the sidewalk, Sunday morning Lies a body oozin' life Someone's sneakin' 'round the corner Is that someone Mack the Knife?!

Go Grover!: I don't fully grasp it, but, I'm sure it's a lovely sentiment.

( I Love Trash finishes playing and laughs as Go Grover! exits.)
