Mark Twain's description of the Arno River in Florence, Italy:

"It is popular to admire the Arno. It is a great historical creek with four feet in the channel and some scows floating around. It would be a very plausible river if they would pump some water into it. They all call it a river, and they honestly think it is a river, do these dark and bloody Florentines. They even help out the delusion by building bridges over it. I do not see why they are too good to wade."
