The Bullwinkle Show (1959)

Season 1: Episode 45

If only they knew the whereabouts of another mooseberry bush! Perhaps the moon men will tell them, but when our heroes go to New York to call on Gidney and Cloyd, all they find is a theatrical newspaper with the headline: MOON MEN SOCKO IN LOS WAGES! BOFFO B.O.! Sure enough, Bullwinkle baby, the moon men have gone Hollywood, but they take time out from taking bows to take a long-distance call backstage and clue the moose in: There's a mooseberry bush to be found in Pottsylvania, a menacing little land that just happens to be where Boris and Natasha are from!
