I know this is really more of an April Fool's Day-type thing, but it applies here too.
Today at work, my boss told me to go out on the roof of the school to clean off some of the over-thrown recess balls. As a good employee would, I leaped out the window onto the roof without hesitation. No sooner did I plant my feet firmly on the rocky rooftop when I realized what was about to happen. Despite my immediate effort to return quickly to the only survivable escape option at the lone window, I spent 20 minutes of my day on the roof. It was like Christmas eve somebody stole the sleigh, and I was Santa.
Although I could watch them laughing hysterically from the locked window during my encampment upon the rooftop, the real joke was on them. I'm fairly certain that they were too stupid to realize that I was still clocked in while I was locked out. While they were busy stripping floors and painting walls, I twiddled my thumbs. Despite my embarrassment, I managed to snag a paid 20-minute break; I surely won't argue with that. At the end of the day, my reputation was a tad tarnished, but my spirits were high, knowing that while they got a quick laugh I got the ripe end of the deal.
