I suppose you could ground yourself with the metal plug part of a USB, if the computer itself is grounded when plugged in to the wall. I don't know where you are, but DealExtreme ships worldwide and has free shipping, so you could order one of the anti-static bracelets for $1.80. Also, grounding yourself on anything large and metal works well, or thru the ground hole of a wall socket (or better, so you don't accidently electrocute yourself with the wrong hole, usually the screw holding the wall socket face cover is grounded).
