absent-minded

I am just finding this term, "absent-minded" so funny today. I don't know maybe it's from lack of sleep, but it just cracks me up. "Roll-call! Okay, Heart? 'here!' Lungs? 'here.' Eyeballs? 'present!' joints? 'here!' Brain? 'here!' Mind? ... Mind?" My mind is absent. Missing in action. Taking a sick day. "May my mind be excused today?"
