I like Mitchell also. He was good.

During the 60s there were several character actors who showed up regularly on a number of shows(Above, someone posted the women who did so). Allen Melvin was one. He played a couple of different roles on the Andy Griffith Show and then showed up on The Dick Van Dyke Show.
