You know the kind I'm talking about, here are a few examples...
'Experience is the knowledge that enables you to recognise a mistake when you make it again.'
Flying is hours of boredom, punctuated by moments of stark terror.'
'The probability of survival is inversely proportional to the angle of arrival.'
'A smooth touchdown in a simulator is as exciting as kissing your sister.'
'Remember when sex was safe and flying was dangerous?'
