"Beware Greeks bearing gifts." During the Trojan War, the Greeks pretended they were surrendering and offered a gift of a horse. The gift was accepted and brought through the gates of Troy, but once the Trojans were asleep, the Greek warriors hidden inside the giant horse exited and slaughtered the citizens of Troy. This July 2011 file photo shows a replica of the legendary Trojan horse at the entrance of the archaeological site of Troy, Turkey along Turkey's Aegean coast. (AP Photo/Giovanna Dell'Orto)
