Remember these classic's ? 
Ahh yes...Rocky and Bullwinkle and friends.....
Much more adult than you see at first glance....and not in any kind of innuendo or off color type of script...just that the wording and situations were more adult..some political jabs in three too. Maybe sort of like
Alice In Wonderland.
For example one of the items in the show was the Kerwood Derby.... A hat that turned someone who put it on mediocre. I heard they were sued for it's use by the somewhat uninspiring actor, Durwood Kirby
The episodes were full of hidden humor that most kids would miss.
Had a few years of episodes on tape once.
