Draw a snake and add feet to it

Long long ago,there were some people they bought some wine,and they drinking after a while,there was just a bowl of wine.
And than some one of them say"each us draw a snake and than the fastest drawer can drink the last bowl of wine".And the others all agreed with him.
All of them start drawing,one of them was finish draw a snake very soon.Than he saw other was still drawing.So he say"let me draw some feet on the snake,and after that I will drink the last bowl of wine"
During he's drawing, a man was already finish draw a snake and he take the last bowl of wine and finish it,and he say"Whoever has seen a snake with feet? Yours is not a snake." The man who add feet was repent.
