A recent reference to an old TV show called the "A-Team" reminded me of a story I had once heard about Mr. T. I found the details of it on-line in Wikipedia still.
It's a great example of needing to be specific in what we ask for as well as to not underestimate people.
In November 1975, Tureaud was awarded a letter of recommendation by his drill sergeant, and in a cycle of six thousand troops Tureaud was elected "Top Trainee of the Cycle" and was also promoted to squad leader. In July 1976, Tureaud's platoon sergeant punished him by giving him the detail of chopping down trees during training camp at Fort McCoy in Wisconsin, but did not tell him how many trees, so Tureaud single-handedly chopped down over seventy trees from 6:30 am to 10:00 am, until a shocked major superseded the sergeant's orders.[9
