Round Tones, Round Tones.

Rattus: I say, old thing, I've heard you sing and I think you could use a refresher course on proper annunciation. Now repeat after me.
"Arround the rrocks the rrugged rrascal rran."

Tea Rat: "Aroun th' rum th'e ragged ruscal rocked."

Rattus: My word, this is worse than I thought. Pay attention. And remember, round tones, round tones. And trill your r's. Now again.
"...the rrugged rrascal rran."

Tea Rat: "...thum rascul rigg-ed racked."

Rattus: Forget that one. Try this.
"Sinful Ceasar sipped his snifter
seized his knees and sneezed."

Tea Rat:
"Simple Simon saw a sinner
seized his snout and screamed."

Rattus: You're infuriating. Round tones, round tones. Try this, in honor of our friend Mozes.
"Mozes supposes his toeses are roses
but Mozes supposes erroneously."

Tea Rat:
"But Mozes he knowses his toeses aren't roses
as Mozes supposes his toeses to be."

Rattus: You cheeky blighter. You've been pulling my leg?

Tea Rat: "Rattus realized really being raked." Here you try this one:
"Bricka - bracka - cheese and cracker siss boom ba
Tea Rat, Tea Rat, rah, rah, rah."

Rattus: I'll say no such thing.
