Off the top of my head

Posted by Cilla Wykes on July 11, 2000

Can anyone tell me the origin of this expression? My boss at work insists that the expression was invented by him! Is he simply arrogant, strange or is he right? Can anyone find the expression used anywhere (by shakespeare or someone equally famous would suffice!) so I could confront him with a few facts?

Any help would be greatly appreciated.
