I've never had this happen with a laptop but as a musician I've been zapped by a microphone a bunch... not an infrequent occurrence if you play electric guitar and sing at the same time. Twice in the past year I've been hit during soundcheck at a gig because of bad grounding at a venue. Last time my solution was to plug everything into the same outlet via a power strip but I invariably end up off-kilter for a few minutes after being electrocuted through my mouth as I'm about to play :-(
