You better watch out. You better not cry. You better not pout. I'm telling you why.
The eve before the Feast of St. Nicholas is Krampusnacht. Before Jolly St. Nick comes to give all the good girls and boys their gifts, a black and hairy creature appears, visiting the homes of the wicked and giving them theirs. Only his gifts are those of coal or whippings with his birch sticks. If you've been very bad, he might scoop you up and take you down to the river and dump you in - and for the very wicked children, they go back to hell with him.
