Cartoons aren't just for kids. As a matter of fact, as an adult, you get to enjoy them even more than you would as a kid. For example, you can compare your favourite celebrities to the charactes on the show. Or imagine what the characters would look like as real-life people.
But most importantly, once you're all grown up, you're able to catch all the dirty details the show's creators put in there for the adult's amusement. Like SpongeBob making shower sex jokes, or women on Johnny Bravo referencing their kinks.
Yeah, this changes everything. Childhoods ruined.
