The Bullwinkle Show (1959)

Season 1: Episode 90

Boris and Natasha take off in terror, but, unzipped, the menacing Snowman turns out to be two moon men in disguise. After their great show business success, they explain, the two were signed to do a TV western, Moonsmoke, but when Marshall Cloyd inadvertently drew his scrooch gun and fired into the camera, the entire home audience was glued to their seats, so naturally the moon men were canceled in favor of beaming round-the-clock commercials at their captive audience. Now that our heroes finally have a mooseberry bush, will Rocky do his duty to his government, or will he let the homesick moon men use it to get back to their home crater?
