By The Barrel

“Never pick a fight with someone who buys ink by the barrel,” slurred Mark Twain, staggering drunkenly in the street.
“Certainly, sir,” said the police officer. “But I think you’ve had too much to drink.”
“That’s because I buy wine by the barrel,” said Mark Twain, falling flat on his face in the dirt.
The officer dragged Twain back to the hotel lobby, and that’s when the newspaper office exploded.
“Great Scot!” shouted the cop.
“I also buy black powder by the barrel,” mumbled Twain. “That’ll teach the son of a bitch to be late paying me for my articles.”
