Making Murphy’s Law Work for you:

This is really amazing, but I’ve found a way to make Murphy’s law work for me. The elevator nearest my office usually takes a half minute or more to arrive after I push the button. But when I walk to the elevator, if I have some trash in my hand, say, a banana peel, I press the elevator button and walk further to a trash can eight steps beyond. The elevator always seems to arrive when I’m furthest from it - right at that trash can - so I drop in my peel and run back to the elevator, catching it a lot sooner than if I’d just stood there, waiting for it. Really. Trust me.
