Do that round here and you'll get more than embarrassed - more like
several hundred volts!

Or 25,000v if you measure the height to the overhead lines. (Just
500vDC for trams though.)

I've just been out measuring the height of a 500kV power pylon. For
some odd reason the measuring tape exploded. I'm going to take it back
and complain to the DIY store tomorrow.
