The Adventures of Tom Sawyer by Mark Twain Chapter 1 Page 18

“You’re a coward and a pup.

I’ll tell my big brother on you, and he can thrash you with his little finger, and I’ll make him do it, too.”

“What do I care for your big brother? I’ve got a brother that’s bigger than he is — and what’s more, he can throw him over that fence, too.” [Both brothers were imaginary.]

“That’s a lie.”

“Your saying so don’t make it so.”

Tom drew a line in the dust with his big toe, and said:

“I dare you to step over that, and I’ll lick you till you can’t stand up. Anybody that’ll take a dare will steal sheep.”
