So as you may have guessed from its title, the episode in question dealt with Mr. Snuffleupagus, Big Bird's woolly mammoth friend, coming to terms with his parents splitting up. The show did its best to explain to kids how, despite Snuffy's parents no longer living together, they still love him and his kid sister Alice, who definitely won't have to move away to Basil Boulevard or anything like that. Unfortunately, after watching the episode, the preschool test audience reportedly thought that, no, divorced parents did no longer love their kids, that divorce did mean losing all your friends, and that your folks arguing did automatically signal the end of your family.
Some confused kids even saw Snuffy's sister angrily hitting her teddy bear and somehow got it into their heads that she stabbed it with a knife. Holy s**t! Now we have to see this thing.
"So ... is she single?"
We'll probably never get our chance, though -- in the end, despite sinking months of research and God knows how much money into the episode, Sesame Street decided to not unleash it on the general public, and probably fed all of its remaining copies to Cookie Monster. To this day, only the 60 children in the test audience have seen the divorce footage, and we imagine most of them have repressed most of it since then.
