M*A*S*H Easter Egg - The Moon Is Blue/State Fair

In the episode The Moon Is Blue, Hawkeye and B.J. spend the episode attempting to get a copy of a dirty movie, "The Moon Is Blue," to show on movie night. Inadvertently, their film is switched with an excruciatingly clean old movie called "State Fair," which they proceed to boo and heckle. The inside joke? Harry Morgan, who played Colonel Potter on M*A*S*H, also appeared in "State Fair." His character, however, was not featured in the clips shown in the M*A*S*H episode.
