A snippet at the very beginning, much more at 0:44 -- really does look like jb in a tizzy over cadcam he don't unnerstand, eh? Also, 3:20 -- jb being chased, assaulted at a mastercam/SW training session? Really, quite a likeness, bald spot and all.
Hormone therapy would explain jb's intermittent snits, near-meltdowns, and general BizarroLand behavior, logic.
I guess, from rehab pov, all these muthafuckas could go into the bar/lounge/stripper/entertainment biz, eh?
