"Ain't I ever goin' to get a turn at my own horn?
Here you've had two turns, Penrod, and even Sam Williams--" Sam's petulance at once directed itself toward Roddy partly because of the latter's tactless use of the word "even," and the two engaged in controversy, while Penrod was left free to continue the experiments which so enraptured him.
"Your own horn!" Sam sneered.

"I bet it isn't yours! Anyway, you can't prove it's yours, and that gives me a right to call you any--" "You better not! It is, too, mine.

It's just the same as mine!" "No, sir," said Sam; "I bet you got to take it back where you got it, and that's not anything like the same as yours; so I got a perfect right to call you whatev--" "I do NOT haf to take it back where I got it, either!" Roddy cried, more and more irritated by his opponent's persistence in stating his rights in this matter.
"I BET they told you to bring it back," said Sam tauntingly.
"They didn't, either! There wasn't anybody there." "Yay! Then you got to get it back before they know it's gone." "I don't either any such a thing! I heard my Uncle Ethelbert say Sunday he didn't want it.

He said he wished somebody'd take that horn off his hands so's he could buy sumpthing else.

That's just exactly what he said.
