Can anyone tell me the 成语 about the snake? The story goes that this group of guys were having a contest for who could draw a snake the fastest. The guy who was first, he started to draw legs on the snake, but in the end he lost cuz snakes don't have legs. Basically the proverb means "to be superfluous" or something.. I just can't remember it!! I want to incorporate it into my Ancient Civs ISU presentation, if I can find it. Any other proverbs with cool stories behind?
