Cold Comfort.
Visitor to the West Indies (who has been warned against bathing in the river because of alligators, but has been told by the boatman that there are none at the river's mouth). "By jove, this is ripping! But, I say, how do you know there are no alligators here?"
Boatman. "Well, you see, sah, de alligator am so turr'ble feared ob de shark!"
