We all know about Paul Revere's famous ride. Did you know his horse's name - Brown Betty. Now you do.
Did you know that the horse ridden by James Arness (Matt Dillon on Gunsmoke) was the same one ridden by Lorne Greene (Ben Cartwright on Bonanza)? Its name was Buck on both series, but its real name was Dunny Waggoner and Greene bought the horse after his series ended.
Ulysses S. Grant's horse was named Cincinnati, and Custer's horse was Vic, who died with his master at Little Big Horn. OK, I am finished horsing around.
