The mom from Leave It to Beaver secretly voiced this Muppets character

Barbara Billingsley is the bridge between '50s and '80s kids.

Kids who grew up with Leave It to Beaver in the '50s and '60s have more in common with '80s kids than either generation may have realized. The unexpected bridge between the two? Muppet Babies, a delightful Jim Henson cartoon that aired on CBS from 1984 to 1991.

Jim Henson's Muppet Babies imagined the most beloved Muppets characters as tiny tots penned together in a nursery, where they shared one kind-natured Nanny who overlooked them all. What '80s kids would be too young to recognize and '60s kids may never have tuned in to hear is the fact that the Nanny was voiced by one of TV's most cherished sitcom moms, Barbara Billingsley, who played June Cleaver on Leave It to Beaver. Watch the opening credits below and listen about 40 seconds in for Billingsley's voice.

Billingsley's sitcom from the 1950s today is synonymous with a simpler time, when adventures like those Beaver and Wally share on the show led to important lessons delivered lovingly by Billingsley and her costar Hugh Beaumont, playing Ward Cleaver. Similarly on Muppet Babies, little Kermit, Fozzie, Animal, Piggy, Rowlf, Gonzo and more imagine terrific adventures that drive the plots of each episode and any time their daydreams get too scary, the scene is soothed by the appearance of Nanny, shown always just from the shoulders down. That makes Billingsley's a voice that soothed several generations.

Both of Billingsley's shows were hits with kids, and both left their own cultural legacies, garnering Emmy nods (and seven wins for Muppet Babies) along the way. That explains why in this time of reboot madness CBS will be rebooting Muppet Babies this year, due to premiere in March 2018 on Disney Junior. The actress Jenny Slate has been cast in Billingsley's role as the new Nanny, stepping into some very large shoes, already well-worn in from the road Billingsley traveled from Leave It to Beaver to Muppets icon.
