A mate of mine who played in a band got shock off a mains plug when setting up on stage ..... It was a cable with a mains plug on both ends!
That cable is known as a widow maker. The are so stupidly dangerous it is untrue, and there really is no excuse for ever making one.
When we moved into our current home ... I found one of the sockets in the kitchen was on the end of a very significant T&E cable traight back to the fuse box. The previous owners had decided to move the cooker .... and had simpley swapped the cooker outlet with a double socket ... sorted!
Nothing wrong with that at all. Quite common infact.
