People tend to remember cartoons they enjoyed watching as a kid, even the ones they saw only a time or two, so if nobody remembers a certain cartoon it's probably because watching that toon has caused mental scarring.
But memory is a tricky thing, and sometimes we repress our show-related memories because that horrendously awful show featured characters we want to continue liking.
The "funky fresh" Hanna-Barbera reboot called Yo, Yogi! is a good example of a show that's best forgotten so we can go on liking those classic 'toons the way they were before the dumbification.
Dorkly has put together an erroneously titled collection of 15 Retro Cartoons That Literally Nobody Remembers, and besides the bad titling the list includes three shows that never really existed. See if you can figure out which ones are fake!
