15+ Dumb Cartoon Characters That Will Leave You in Stitches!

Ed is a character from the animated television series “Ed, Edd n Eddy.” He is known for his simple-minded and easily distractible personality.

Despite Ed’s lack of intelligence being often played for comedic effect in the show, it is important to note that he is not necessarily dumb.

Ed’s intelligence level can be attributed to his lack of focus and attention span, common traits of individuals with Attention Deficit Hyperactivity Disorder (ADHD).

While the show does not explicitly state that Ed has ADHD, his behavior and traits are consistent with those of someone with the disorder.

Meet Patrick Star, the lovable yet dumb-witted starfish from the hit animated TV show SpongeBob SquarePants! In this hilarious series, the character claims to be the master of doing nothing, and boy, does he live up to it.

Now, it’s hard to say exactly what’s happening in Ralph’s head.

Some say he suffers from intense learning and developmental disabilities, while others believe he might have some form of childhood psychiatric illness.

Whatever it is, the spirit of his mentality is kept rather ambiguous – and that’s part of what makes him so intriguing!

Throughout the series, Chris is often shown to be the dumb character and the butt of the joke, with his lack of intelligence and poor decision-making skills leading to many mishaps and misadventures.

For example, he is known for making stupid choices like attempting to drive a car without a license, joining a cult, and even mistaking a urinal for a drinking fountain.

Ladies and gentlemen, let me introduce you to one of the funniest. The most dim-witted character to ever grace the small screen – Peter Löwenbräu Griffin, aka Justin Peter Griffin!

As an essential member of the popular American animated sitcom Family Guy, Peter is the husband of the lovely Lois Griffin and the proud papa of three kiddos – Meg, Chris, and Stewie.

With his oversized pink nose and bright orange-ginger hair, Billy stands out from the crowd in all the right ways.

He’s known for his cheesy pickup lines, his love of his reflection, and his tendency to mangle just about every task he takes on.

Let’s talk about one of the most entertainingly dumb characters in cartoon history – Dee Dee from Dexter’s Laboratory! This pink-clad, the ditzy character is the best friend and neighbor of the boy genius, Dexter, and she’s known for being a bit of a pest – much to Dexter’s annoyance.

Hold on to your donuts, folks, because I’m about to tell you all about the one and only Homer Jay Simpson – the beloved (if not the brightest) major character from the iconic sitcom, The Simpsons!

He’s always getting into trouble with his clumsy, bumbling ways and can’t seem to do anything right. But despite his numerous flaws, we can’t help but love him.
