Mr. Ed was the best. Just ask Wilbur.

Alan Young, 73, spent five seasons in the '60s playing Wilbur Post, the guy who talked to his horse on TV's "Mr. Ed."The horse was the best actor he ever worked with, Young said Thursday during a three-day fan convention in Knoxville, Tenn. "He didn't upstage you. He knew his lines. He got there on time," Young said.

So how did Ed talk? It was a closely guarded secret. "I created the lie that we used peanut butter," Young said, but "we used a soft piece of nylon under his lip, which he tried to work out."

Western B-movie star Allan "Rocky" Lane supplied the voice.
