Misted Ed, Mister Ed
Mister Ed isn't just a horse, of course. He's a horse who can talk! He may not be as majestic as Black Beauty or as heroic as the Lone Ranger's Silver, but Mister Ed has a sense of humor.
Over the course of six seasons, Mister Ed only talks to his owner, Wilbur Post, which gets Wilbur in all sorts of hot water with his wife, Carol. This mischief-making equine also knows how to use the telephone. Top that, Flicka.
