Reset button.

I'm having one of these implanted on the side of my head.
Apparently it's a lot easier and cheaper than going into witness protection.

It means other people can reboot me everytime I do something
unsavoury and unpleasant. I wanted the button in my arse crack
but they couldn't find any surgeons willing to go there.
Even a blind, mad surgeon they found amputated his own head
rather than give it a go.
