Who would win? As much as I like Mr. Ed, I’d have to put my money on Francis, what with his powerfull friends.
Who would win WHAT? A pie-eating contest? A joke contest? A plow-pulling contest? Thumb wrestling?
Pin the tale on the mod-
er, fisticuffs.
Horses can’t make fists.
But, the Mule’s Army friends would kill and eat Mr. Ed.
Francis:
sterile
hung out with war mongers
Dingy dark hair.
worked for Dell [sub] comics[/sub]
Mr. Ed:
Cultured- via Wilbur, was trained in the classic art of architecture.
Zippy theme song.
Blonde and dashing!
Liked Apples!
Oh baby, I pick ED!
No, but they can bite like a sonofabitch.
I must agree with BNB’s reasoning as to how she choose Ed, though perhaps without the “Blonde and dashing” bit. 
Ed was more aware of his surroundings, IMHO.
