Well here's a joke:

So there's a German guy, a Spaniard, a Jewish guy, an Englishman, and a Frenchman, going to a street magician's performance. The magician notices that they all wear glasses, thus have bad eyesight. The magician asks them to move forward a few paces, then says, "Can you see me now?", to which the group replies:"Yes.", "Oui.", "Ken", "Si", "Ja" ๐Ÿ’€
