1. Dennis the Menace
Dennis is a menace who terrorizes his neighborhood, and one elderly man in particular, poor Mr. Wilson. Yet Dennis's parents don't seem to have a problem with the fact that he always carries a slingshot in his pocket. Nowadays, this menace would find himself in juvenile hall by his sixth birthday.
2. George Jetson
George Jetson always seems to be irritated and angry, which often leads to him yelling and screaming at his wife. I would assume his neighbors would have heard at least a few of these tantrums. If his temper didn't get him arrested for domestic violence, his mistreatment of Astro, the family dog, would make him an obvious target of various anti-animal-cruelty societies.
3. Bam Bam
As with the case of Dennis the Menace's slingshot, no one in Bedrock seems to be concerned that Bam Bam always carries a club. Nor do his parents appear to be concerned with his frequent displays of aggressive and violent behavior. Bam Bam has no regard for others' safety, and today this would cause him to be in counseling and/or medicated for his ADHD.
4. Nelson Muntz
One of America's most beloved bullies, Nelson's "haw, haw" is one of TV's most iconic catch phrases. But he is a bully and, with anti-bullying legislation being passed in every state, it is safe to assume that Springfield would fall under similar laws to protect children from all forms of bullying. So, Nelson would likely find himself under the watchful eye of a child psychiatrist, medicated, or placed into a special class with students who have similar aggression issues.
5. The Little Rascals
Who doesn't love a bunch of cute kids who always seem to be up to no good, causing mayhem wherever they go? Well, that kind of reckless vandalism and disregard for common courtesy doesn't sit too well with people in the present. They would be rounded up by the police in five minutes. Not to mention, they have a dog that is obviously not registered nor neutered.
6. Pepe Le Pew
In every cartoon we've ever seen of Pepe Le Pew, he's chasing a female and not taking "no" for an answer. In today's world, we call that stalking, and this would likely result in a restraining order.
7. Wile E. Coyote
In a day and age with a lingering fear of terrorist attacks, when even saying the word "bomb" can result in a heavy fine and some jail time, anyone with unlimited stockpiles of dynamite and rockets would be very suspicious to the FBI. His reckless behavior and obsession with explosives would make him a serious national concern.
8. Elmer Fudd
We all love Elmer's antics and can quote his iconic phrase: "Be very, very quiet. I'm hunting wabbits." But with all the hunting laws and regulations today, I have to believe that Elmer's obsession with hunting "wabbits" year round would definitely not always coincide with official rabbit-hunting season and regulations.
9. Donald Duck
Donald Duck is one of Disney's most beloved characters, and he's also one of history's most confusing cartoons. The big question often asked in reference to Donald is not about his apparent speech impediment, but "Why does he wrap a towel around his waist when he gets out of the shower, but he doesn't wear pants?" It would be safe to assume that Donald's exhibitionism would get him locked up for indecency in nearly any town or city.
