A tour group stopped at the Tower of London, and were given the chance to try out some of the ancient armour. Two men - one from Prague and another from Athens took up the opportunity. One donned a slightly damaged suit of plate armor and the other chain-mail, while the rest of the group crowded around. But in the full suits, the onlookers couldn't tell one from the other.
"Is that the Czech wearing the plate armour?" asked one tourist.

"No," replied another, "The Greek has the broken plate, and the Czech is in the mail."
