Still tidying papers, and found this good joke:

A team of archaeologists was excavating in Israel when they came upon a cave. Written across the wall of the cave were the following symbols, in this order of appearance:

A woman - A donkey - A shovel - A fish - and the Star of David.

They decided that this was a unique find and the writings were at least three thousand years old. They chopped out the piece of stone and had it brought to their museum, where archaeologists from all over the world could come to study the ancient symbols. After months of study, they held a press conference to reveal the results of their work.

The president of the archaeological society stood up and pointed at the first drawing and said, “This looks like a woman. We can judge that the race was family-oriented and held women in high esteem. You can also tell they were intelligent, as the next symbol resembles a donkey - indicating 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 lies in the symbol of the fish, which means that if a famine had hit the earth, meaning land-based food sources failed them, 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. Suddenly a little old man stood up in the back of the room and said, “Idiots! Hebrews read from right to left. It says, ‘Holy Mackerel, Dig the Ass on that Woman!’”
