Burned or zapped? Light bulbs get thermally hot but glass is non-conductive.

I haven't personally been bitten by 240V but from people I've talked to who have, I don't intend to chance it happening.

I'd guess you could get zapped if you accidentally touch the metal part of the bulb (or the socket) while unscrewing the old one or screwing in the new one.
