My favorite DON'T DO THIS method is plugging European plug in UK socket - using something like scissors in earth to open shutters for neutral/live where EU plug actually fits pretty ok.

The other one is twisting US/JP plug pins so they fit AU/NZ sockets...

If it's one of those lovely old MK sockets like you used to get in the 70s/80s, then the earth pin doesn't open the shutter - it's opened by equal pressure on the phase and neutral pins. It takes a bit of jiggling to get the Euro plug to go in.

I keep both Schuko and UK kettle leads, cloverleaf leads, and figure-8 leads in my laptop bag, having been stuck before.

The best part is that you need to do this when you're on holiday, so all you've got are your keys, so you stab the keys into the slots and ever so carefully balance the round European plug contacts onto each key, and you pray to god that there's no earthquake and you don't cause a fire.

Or so I heard someone else do.
