I was hoping from the title I'd have the best story, but my dumbassidness comes from poor planning. I have never done something to cause myself or anyone else pain, on purpose. And I certainly won't try again when it fails.

Like this one time I was in tree and thought it would it be awesome jump to another tree. And of course I thought I could make it. But I didn't and I failed hard. Yes I meant failed instead of fell.
