The what??

As an aside from yesterday's post - why do we call it a "Trojan horse"?  If you know the story you will know that the horse was in fact constructed by the Greeks and left outside the city of Troy for the Trojans to find and bring inside the city, whereupon the few Greeks concealed inside it crept out under cover of darkness and opened the gates to let in the Greek forces who then took the city. So if there's any logic, it should be called the Greek horse - the Greeks themselves by the way just refer to it as the wooden horse.
