KNOXVILLE, Tenn. (AP) _ 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.

``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 for years.

``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.
