“Anything that can possibly go wrong, does”
“Buy a house in a foreign country and, it seems, that anything which can go wrong usually does.”
“Anything that can go wrong, will go wrong”
“The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at or repair.”
“What could possibly go wrong?”
“Anything is possible. Anything can be.”
