I happened to see our school principal's badge sitting on a piano when I was cleaning up after an event, so I put it around my neck with the full intention of giving to him. I totally forgot about it and left for the day. It was a weekend, so when I realized I still had it, I thought it would be funny if I put it in a bowl full of Jello. I put it on his desk the next Monday morning and thought I was pretty funny. A few days later, he handed me the same bowl with something he put in Jello from our event the previous weekend. We had a good laugh with the office staff and a bunch of teachers that knew about it. It was pretty funny.
