Taking a shower in a electrical storm (thunder and lighting) - why is it bad?

Ever since I was young I heard people say it was bad to take a shower when it was lightning outside. I understand that water is a good conductor of electricity (hence the reason you don't use an electrical product in the presence of water (i.e. hair dryer in a bathtub)), but has there ever been an occurance of lightning striking someone in the shower? Wouldn't it be reasonable to think that precautions have been made to prevent this anomale in more recent times? I'm really curious.

It's not anything I've heard any particular instances of, and I'm a regular reader of the "Strange Deaths" column in Fortean Times, so I think that this falls under the category of "Highly Unlikely But Theoretically Could Happen in a Freak Accident."

The reason people talk about it is probably because it's much easier to imagine happening than, apparently, it would be to _actually_ happen.

The internet says that lightning can hit your house and travel through pipes and other stuff like that. If you happen to simply touch the appliance or faucet. You will be electrocuted.

Hope this helped.

I don't think it is bad. (I like the way you framed the question too - possible urban legend)

I can foresee no way for lightning to cause a sufficient voltage drop between a showerhead (already connected to the ground through low-resistance conductor) and a person (also connected to the ground) to cause flashover.

Nothwithstanding some really poorly designed experiments conducted by the 'mythbusters'
