Okay, this was my sister.
They were getting ready to do a "horse race" no one knew what is was when they asked for volunteers... since my sis had that crazy hat on, they called her up, and 5 others some young, some older.
They gave everyone a horse on a stick and said when your number comes up, you have to gallop that many times.
When you are done yell.... "Yeeee Haaaaw"
It was hilarious.... I doubt she'll jump up so easily next time.
Here's the link, by the way prior do the race they all had to prance around with the horse between there legs and try and get people to bet on them. She was horse #1 and came in 3rd place.
