Grimm's Household Tales

A man and his wife were once sitting by the door of their house, and they had a roasted chicken set before them and were about to eat it together. Then the man saw that his aged father was coming, and he hastily took the chicken and hid it, for he would not allow him to have any of it. The old man came, took a drink, and went away. Now the son wanted to put the roasted chicken on the table again, but when he picked it up, it had become a great toad, which jumped into his face and sat there and never went away again. If anyone wanted to take it off, it looked at him venomously, as if it would jump in his face, so that no one dared to touch it. And the ungrateful son was forced to feed the toad every day, or else it fed itself on his face; and so he went about the world without knowing rest.
