Somewhat OT, but I actually liked that talk. You know Steve Jobs does the same thing at home when he is alone, except the chant is "Jobs, Jobs, Jobs, Jobs, Jobs". And it's not the underarm region that gets stained.
When he's not "unveiling products" or berating his minions, I always imagined him sitting full-lotus on a tatami mat, alone in an empty room, staring intently at the wall.
