I'll share a few.
In college I was woefully unprepared to take a Final Exam, so I just skipped it, then came in to the next class wearing a knee brace. I told the prof. that I had suffered a skiing accident and asked for a makeup date. He gave it to me, but I wore that brace to every class for 2 weeks just to make the story stick.
My sis asked me to be godfather to her first son. Because I hadn't been to church in decades I was required to go talk to the current priest at my old parish so he could confirm I was a Catholic in good standing. When he asked me why I hadn't been to church in so long I gave him a story about being a dissillusioned Catholic who had lost his faith but wanted to get it back. He gave me a pass. A year later my brother asked me to be godfather to his oldest daughter. I hadn't been to church all year, so of course I was required to get an OK from the same priest I'd told I wanted to renew my faith a year earlier. This time I got all Drama Queen on him, talking about the unfairness of life and how could a God exist that let's so many horrors exist in the world. He gave me a pass. I'm hoping I'm not asked to be a godfather again because i don't think I could pull off another performance.
Then there was the time I went to interview for a job working in the cash cage if a casino. I came into the reception room, introduced myself and sat down. They were behind on interviewing and eventually after a longish wait I had to use the bathroom. While there, I accidentily "dripped" on my new light khaki pants. Just a few drops, but noticible, right there on the front of my pants.
I made it back into the reception room without anyone noticing and walked over to the water cooler. I pored myself a glass and sat down, in the process I faked spilling the water into my lap. Everyone was embarrassed for me and therefore very nice about it. People got me towels, I was even bumped up in the interview process. The HR person interviewing me was very understanding and it actually worked out to be a decent ice breaker, In the end I got he job!
Hahaha. Those are excellent stories. A friend of mine once used an lie to get out of taking his final exam in college. He kept using the excuse that one of his relatives died, and he was too bereaved to go to class. He did this in different classes every semester.
We had a running joke, where I'd ask him every time, "So who died this year?" or I might say, "Damn Andrew, do you have any surviving family members left?" lol.
