The chief mate of an old wind jammer was on the quarterdeck peering through the telescope at the horizon when he was approached by the galley boy who asked him what he was looking at.
The mate replied: "I'm looking for the Equator, and I believe I've found it. Would you like to see it?"
"Yes, sir," answered the boy, quite excited.
As he squinted through the scope with one eye open, the other closed, the mate slyly plucked a hair from his long beard and held it across the sighting glass saying, "There now, can you see the Equator?"
"I sure can!" exclaimed the lad. "And what sure I can see a camel walking on it!"
