It makes me smile when the quaterback runs the ball. It takes a lot of cojones to rush out of the pocket, and I appreciate that. When it's intentional, it's called the "Quaterback Draw". When it's spur of the moment, it's awesome.
"A variation of this play [Draw Play] is the quarterback draw, where the quarterback himself runs the ball, instead of handing it off, meaning the running back is free to help block." Wikipedia
