not working on a cab, but i got a nasty electric shock;
about 5 years ago i was working on the computer (music essay for school) and needed to plug the printer in, so i crawled under the desk to get to the socket, but it was a dodgy plug (for those of you not in the uk, we have 3 pins on or plugs, 2 of which should be half covered in plastic (nearest the plug) so you can't touch them while plugging in - this one didn't, and was quite a small plug)
anywho, i don't remember anything after crawling under the desk - my parents said they heard a bang (which could of been my head hitting the underside of the desk) - they came into the room to find me spazzing out
next thing i remember was coming round in the kitchen, feeling really spaced out, with my dad trying to stop me from falling over.
ambulance came, and i spent the night in hospital, felt really sick and shaky (wanted to barf)
but i havn't had a headache since!
