There was a tour bus in Egypt that stopped in the middle of a
town square. The tourists were all shopping at the little stands
surrounding the square. One tourist looked at his watch, but it
was broken, so he leaned over to a local who was squatted next to
a camel.  "What time is it,  sir?"

The local reached out, softly cupped the camel's genitals in
his hand, and raised them up. "It's about 3:00." he said.

The tourist couldn't believe his eyes.  He ran back to the bus,
and sure enough, it was 3:00.

He told a few of the fellow tourist, "That man can tell time by
the weight of the camel's balls!"

One of the doubting tourists walked back to the local, asked him
the time, and the same thing happened! It was 3:03 p.m.. He ran
back to tell the story.

Finally, the bus driver wanted to know how the local did it. He
walked over and asked the local how did he know the time from the
camel's testicles.

The local said "Sit down here and grab the camel's testicles.
Now, lift them up in the air.  Now look underneath them to
the other side of the courtyard where that clock is hanging on
the wall."
