AAAAGGGHHH! Whew, that scared me too!!!
My dad would have to go in occasionally for a stress test, and they had to shave parts his chest for the electrodes. First time the nurse commented "Hmmm...looks like a double razor job!".
Couple of years later he had to do the same thing. Same nurse, same comment.
I can only imagine that they had a whole garbage can full of gap-toothed razors by the time they were done done with John!!
