A team of archaeologists was excavating in Israel when they came upon a
 cave. Written on the wall of the cave were the following symbols in order
 of appearance.
 1.  A woman
 2.  A donkey
 3.  A shovel
 4.  A fish
 5.  A Star of David

 They decided that this was a unique find and the writings were at least
 more than three thousand years old.  They chopped out the piece of stone
 and had it brought to the museum where archaeologists from all over the
 world came to study the ancient symbols.
 They held a huge meeting after months of conferences to discuss what they
 could agree was the meaning of the markings.  The President of their
 society stood up and pointed at the first drawing and said:
 "This looks like a woman.  We can judge that this race was family oriented
 and held women in high esteem.  You can also tell they were intelligent,
 as the next symbol resembles a donkey so, they were smart enough to have
 animals help them till the soil."
 "The next drawing looks like a shovel of some sort, which means they even
 had tools to help them.  Even further proof of their high intelligence is
 the fish which means that if they had a famine hit the earth, whereby the
 food didn't grow, they would take to the sea for food."
 "The last symbol appears to be the Star of David which means they were
 evidently Hebrews."  The audience applauded enthusiastically and the
 President smiled and said, "I'm glad to see that you are all in full
 agreement with our interpretations."
 Suddenly a little old man stood up in the back of the room and said, "I
 object to every word.  The explanation of what the writings say is quite
 simple.  First of all, everyone knows that Hebrews don't read from left to
 right, but from right to left... Now, look again... It now says:
"Holy Mackerel, Dig The Ass On That Woman!"
