I had gone with my family to Disney MGM Studios for a weekend. On the long ride there (it takes four hours) I felt a little sick to my stomach. Since I didn't feel good I slept the whole way to the park.
When we got there I was still feeling sick, but I put it out of my mind because I figured it was just gas. We started riding and when we boarded Star Tours ride for the second time, I knew there was something wrong.
I suffered through the whole ride (the shaking and jerking of the ride didn't help any) and just as we were getting off... SPLAT!!!! I had an accident, and the most horrible smell came from my pants. I had shit myself in public.
Mom just about ran to the bathroom with me. I got cleaned up and finished my day with no further major problems. To this day we still laugh about that incident. It will forever be one of the most embarrasing moments of my life.
