Why Not?

From The Birmingham Age Herald, July 5, 1915.

A tramp going across a field was accosted by the owner.
“You’ll have to get out of here.”
“Why?”
“Because it’s posted.”
“Who posted it?”
“I did.”
“What right have you to post it?”
“Because it’s mine.”
“Where did you get it?”
“I inherited it from my father.”
“Well, where did he get it?”
“He inherited it from his father.”
“Hm! Where did he get it?”
“He inherited it from his father.”
“Um hm! And where did he get it?”
“He fought for it.”
The tramp took off his coat.
“Well,” he said, “I’ll fight you for it.”
