Anyone trying to tune my guitar is more likely to get a broken arm than a broken string!

Seriously, my 12-string is tuned down five whole frets: I use a "normal" set of strings all moved up one place, with a b-i-g one for the bottom "E" (which is tuned to B) and a normal G to double on the second. I really need to do some work on the nut to make the strings sit better, but I never round to it ...
