Found this thought it was kind funny.
Quarter horses: Definitely jocks. Strutting around flexing those muscles and showing off their butts. Responsible for all the trophies in the glass case.
Paints: Quarter horses with too much make-up.
Thoroughbreds: Preppies. They are athletes never jocks, monogrammed blankets, leather halters, Nike eventer shoes and the latast custom trailer and tack.
Appaloosas: Stoners. The like to drop acid so they can watch their spots move.
Arabians: RAH! RAH! SIS MOOM BAH! GGGOOOOOOOO TEAM!( Need I say more?)
Shetland ponies: Punks. Spikey hairdos, snotty attitudes and any colour of the rainbow.
Friesians: Bikers. Big, buff, always black, cigs hanging out the corner of their mouths and a dangerous glint in their eye.
Morgans: Nerdy teachers pet running around doing everything from yearbook to decorating the gym and rattling the bikers, stoners and jocks.
Drafts (All breeds): No real clique they're just the big guys who sit in the back of the room and fart a lot.
Hackney ponies: Band geeks. Marching along with their heads and knees held high, even going to the bathroom.
Warmbloods: The school staff and faculty. Looking down their noses with righteous indignation and disgust.
Minis: Primary school students.
Donkeys: Would be the teachers with the ability 'to think' and remember what happened the day before. Less likely to step on your feet when dancing.
Saddlebreds: The ones riddled the teen angst, the artsy, drama club type?
Percherons: Cafeteria ladies.
Mustangs: The free spirits and the "rebels without a cause".
The PTA would be aged broodmares only.
Football team: Well the Budweiser Clydesdales of course!!!!
