Here's one from Alex Trenoweth. She has been posting for the last month, and is that rare beast: an astroblogger who lives in the UK. She likes telling jokes. This one is called Mercury Retrograde in the 9th:
A team of archaeologists is excavating in Israel when they find a cave with the symbols of a woman, a donkey, a shovel, a fish, and a Star of David on the wall.
The head archaeologist points to the first drawing. “This indicates that these people were family oriented and held women in high esteem.” he says. “The donkey shows they were smart enough to use animals to till the soil. The shovel means they were able to forge tools. Even further proof of high intelligence is the fish: If famine hit the earth, they would take to the sea for food. The last symbol is the Star of David, telling us they were Hebrews.”
The second archaeologist shakes his head. “Hebrew is read from right to left,” he explains. “It says, ‘Holy Mackerel, Dig the Ass on that Chick!’”
