The electric ambulance.
Something very bizarre happened today.

We parked the ambulance between calls at a spot that happened to be right under some rather low-slung high-tension wires. We were standing outside leaning on the ambulance, when I started to feel a... vibration, sort of. Then some little prickles. "Hey, do you feel weird little shocks?" I asked my partner.

"No, no, what the hell, you're imagining things," he told me. "Although there is sort of this weird... like something's vibrating in there?"

Then, a second later, I got shocked so hard I yelped and jumped away. My partner stared at me like I was a crazy person, then a moment later screamed and jumped. "OW! What the hell is that? OW!"

We had to move the ambulance. But to move it we had to get in, and to get in we had to touch the doors, and the doors are metal. That was a thoroughly unpleasant experience.

Sure enough, when we were out from under the power lines, the shocks went away. Apparently the magnetic field from the power lines had turned the entire ambulance body into an induction-powered EMT-zapping device. Physics At Work. Freaky.
