There's been a script of an episode of this kid's TV show that was supposedly filled with innuendo about how the kids should play with their balls and "twangers" for quite some time now. It goes something like this:
(zippy and george are puppets, bungle is a man in a bear suit and geoffrey is their human friend)
The sketch opens with Zippy peeling a banana...
Zippy: "One skin, two skin, three skin, four"
George: "Zippy, where is Bungle?"
Zippy: "I think Geoffrey is trying to get him up"
If it's all a fake then they did a good job of it.
