Here's a surprisingly old example:
There is an episode of the 1973 Superfriends series where a Professor Goodfellow invents a device called the G.E.E.C., which is supposed to be the ultimate computerized labor-saving device.
The Superfriends have just gone to check it out, and Wendy, Marvin and Wonderdog are walking down the street when a van labeled "Prof. Goodfellow's Funmobile" pulls up alongside them and a voice offers to take them for a ride to meet up with the Superfriends. "Don't be afraid, it's perfectly safe," the voice says, "I am testing a fantastic new invention and I'd like the opinion of some young people, I have everything you like in this van, television, rock albums, ice cream, candy, popcorn", etc., and then finishes with "I have something of great interest to you."
I don't know if this was intentional (it probably wasn't), but it's even crazier considering it was made in a time when Saturday morning cartoons were horrendously watered down for children.
You cannot count how many rules Rocko broke during its first season on ten fingers.
