My old man - who was an electrician and should have known better - used to run any number of applicances off one electricity socket, courtesy of 2- and 3-way adaptors. There was ONE socket in our kitchen, which fed the cooker, the washing-machine, the Flatley clothes-dryer (remember them?), the kettle, mom's iron, the chip-pan and Lord knows how many other things.
Whenever a light-bulb blew, my old man would take it out without switching off, shove his thumb into the holder, and if he got a jolt then he'd announce 'well, the fuse hasn't blown!' His job was installing electric induction furnaces which operated at anything from 2000 volts upwards, so I suppose a dose of household juice at 240 volts didn't bother him...
