Horses: That's Your Big Boy ...

Canadian Clydesdale Poe stands 10 feet tall with his head upright.
Yikes.
Two things -
1. Can anyone ride something so large? If so ... kudos. You've officially earned the title of beastmaster. And I'm intimidated by you.
2. Someone slap a 5'1'' jockey on that thing ASAP. Because, you know, the contrast would be golden.
