(Other definitions for sods law that I've seen before include "Rule that if anything can go wrong it will" , "this means I'm bound to get some!" , "That which suggests that, if something can go wrong, it will!" , "Theory that a dropped slice of bread will always land butter side down, for example" , "'The principle that says that anything that can go wrong will go wrong (4,3)'" .)
