I think it lasted for about 5 minutes. Would the PIC still be OK? At the kids electronics club we fried some 16c84's that way, and I once killed my (at that moment only) 12c509aJW. Since then I put the chip in a round-pin socket, solder a diode to the power pins and plug that combo in wherever the chip is used.
