A man with a look of business on his face came to a hotel-keeper, and asked him if he would buy two carloads of frogs' legs.
"Two carloads!" said the man in amazement. "Why, I could not use them in twenty years!"
"Well, will you buy a carload?"
"No."
"Twenty or thirty bushels?"
"No."
"Twenty or thirty dozens?"
"No."
"Two dozen?"
