Alan Mowbray : Alan Mowbray + M*A*S*H

On an episode of M*A*S*H when the characters begin to watch the film,"My Darling Clementine" I believe that at least two of the characters exclaim very favorable remarks concerning Alan Mowbray.I wonder why,and what the connections are that led to Alan Mowbray being mentioned a few times on this particular episode?

I'm watching that episode as I type this. I imagine it would be like someone putting in a movie and saying "Nicholas Cage is in this!!"
