Shake a leg

Posted by Ed Stansell on September 20, 2002

Your origin on this refers to showing a leg to prove your awake. That may be so, but I doubt it has any connection with "shake a leg". I think a more reasonable explanation of this would be to run. We do sort of shake our legs when we run. In the US, it means to hurry, or make it snappy.
