Marine Corps Fighter Pilot
After his plane was hit and he was forced to eject, the Marine Corps fighter pilot finally regained consciousness. He was in a hospital, in a lot of pain. His friends and family all told him to keep a positive attitude.
While in the ICU, with tubes/IV drips in both arms, a breathing mask, wires monitoring every function and a nurse hovering over him, looking worried. It was obvious he was in a life-threatening situation.
The nurse gave him a serious look, straight into his eyes. Knowing he was not only a fighter pilot, but a Marine, she spoke to him softly and slowly, enunciating each word: "You may not feel anything from the waist down."
Somehow he managed to mumble in reply, "Can I feel your tits, then?"
And that, is a positive attitude.
