One bad-@ss little bug - Is there an entomologist in the house? I don't know what this is

Took a number of pix and vid of this little guy (he's at most 1cm long) this AM, but don't know what he is... know I've seen it before, know I probably "know" it, but with the spasms & pain my body and brain are in, its frequently the case that most of what I "know" is inaccessible to me.
