In 600 BCE the sneaky Babylonians built a large wooden cow that looked like the Egyptian goddess Methyer. They pushed the large hollow cow up to the entryway of Alexandria one evening and ran away waving Le Tricolor.
Thinking they beat Babylon, the Egyptians pulled the goddess statue into Alexandria and started to party. A few hours latter Babylonian soldiers lept out of the hollow cow onto the ground and slaughtered the drunk Egyptians.
(
Later, the Greeks stole the tactic to trick the people in Troy.)
