When I was about 10 years old I was at my second show. I entered in a Walk-Trot Western class. I was riding the snottiest meanest pony which was green broke (not mine! Instructor thought I would be fine riding him) and the pony wouldn't stop trotting the whole class. It finally stopped when he noticed the others in the middle standing and he joined them. Nevertheless my parents were mad at that instructor for even letting me ride that evil thing. It was quite funny now looking back at it though :)
Oh and I got in last place haha.
