Must these be famous quotes or can they be quotes from anyone?
I think my absolute favorite quote is from my BO. We were watching one of the girls who used to board at the barn groom and saddle her horse one day. It literally took her almost two hours. You could tell the horse was getting bored and antsy, so the BO yelled (he's a VERY loud man when he wants to be):
"Get a saddle on that horse or he's going to take a chunk out of your ass!" Words to live by, IMO.
Another one I like is this:
"A good horse sholde have three propyrtees of a man, three of a woman, three of a foxe, three of a haare, and three of an asse.
"Of a man. Bolde, prowde, and hardye.
"Of a woman. Fayre-breasted, faire of heere, and easy to move.
"Of a foxe. A fair taylle, short eers, with a good trotte.
"Of an asse. A bygge chynn, a flat legge, and a good hoof."
--Wynkyn de Worde (1496).
