I remember seeing ...

[seawasp]

... in one of those old "collection of Forteana" books -- I think it might have been Edwards' "Stranger Than Science" -- a bit about human beings who generated high-voltage electricity and/or powerful magnetic fields. We're not talking "scuff across the carpet and startle the cat with static", we're talking "Uncle Fester lightbulb time".

Any modern occurrences of these, and debunking or explaining of same?
