HAHAHA that's an easy one.

I was in class and laid my head down on my desk for a second. The next thing ya know I had that light sleep feeling I was falling and flew up and backwards in my chair, barely catching my desk. The whole class stopped and stared at me (including the teacher). It was so embarassing! I started fake coughing and acting like I had just started choking or something, but it was obvious what had happened *blush*
