The Czechs celebrate St. Nicholas's Day (12/5) with Jesus and the Devil. smileys/wink.gif
Ok, the Devil isn't really celebrated, but parents hire older kids (teenagers) dressed up as Jesus and as the Devil (and maybe angels, too) to show up at dinnertime and ask little kids if they've been good enough to deserve presents from Ježíšek (the Christ Child) at Christmas.
I was pretty floored the first time I came to class the day after and had students tell me with a straight face, "I couldn't finish my homework last night; I was playing the Devil for my niece/nephew/neighbors' kids." smileys/wink.gif
Unsuspecting tourists are also a little unsettled, since the whole city seems to be teeming with teenagers running around dressed in alternate states of holiness/unholiness!
But the Tooth Mouse is a new one on me! smileys/smile.gif
