"Aah..." A patrolling prison guard yawned.
His partner, patrolling alongside him, asked, "What's with all the yawning today? What's going on?"
"My friends invited me out for drinks yesterday. I was out with them until two or three in the morning, and I only got a few hours of sleep before my shift. That's why I'm so tired now," the yawning guard explained to his partner.
"Seriously? You have the night shift, and you still went out drinking that late? It's going to be a long night for you," his partner said, shaking his head.
"Sigh, I'm regretting it now. I used to be able to pull an all-nighter and still come to work the next day feeling great. Now that I'm older, I guess I have to admit I can't keep up anymore..." the yawning guard lamented.
"Give me a break! You're only twenty-seven! If you're old, then what does that make me at twenty-nine? I'm no geezer. I'm still young..."
