Mr. Ed the Zebra?

[AWB]

On http://www.snopes.com, they purport that Mr. Ed, the talking horse was in fact a zebra.

From their page:

Mr. Ed was always referred to as a “horse,” and since the series was filmed in black and white, the viewing audience didn’t notice the difference anyway.

WTF!? A black & white (B/W) animal filmed with a b/w camera is gonna look b/w! There’s no magic cancelling effect!

Is Snopes.com trying to pull a fast one? Debunking ULs on one hand and starting more with the other?
