Irritating Cartoon CharactersRobin
Batman

Lame doesn’t even begin to describe what your life must be like when you spend your teenage years cruising around town with a 35-year-old man, wearing little more than a pair of green leotards. If he had served a better purpose it would have been one thing, but Robin’s primary duty was to get rescued by the Dark Knight while uttering idiotic lines like “Leaping lizards, Batman!” Thanks, but if our life is on the line, we’ll stick with Superman.

Boo-Boo Bear
The Yogi Bear Show

It’s appropriate that Boo-Boo is named after a mistake, because that’s precisely what William Hanna and Joseph Barbera made when they added this pint-sized cub to The Yogi Bear Show. A genuine wet blanket, this blue bow-tie-wearing bupkes always brought the action to a grinding halt, preventing his old pal Yogi from satisfying his carnal need for “pic-a-nic” baskets. And what was the deal with his painfully plodding cadence? If anyone actually thought as slowly as he talked they’d still be deciding what to have for breakfast yesterday. Suffice it to say, this Jellystone Park resident was -- and always will be -- duller than the average bear.

Dennis Mitchell
Dennis the Menace

The very personification of annoyance, Dennis Mitchell was a devilish little imp whose mischievous spirit caused headaches for everyone around him. From the smudge of dirt on his nose to the well-worn slingshot protruding from his back pocket, this spawn of satan was less welcome than mono at a make-out party.

Tweety Bird
Looney Tunes

WeÂ’ve never subscribed to the belief that something is adorable simply because itÂ’s pathetically undersized, and thatÂ’s especially true with Tweety. This cloying yellow canaryÂ’s schtick can be boiled down to a single redundant plot, a tiresome catchphrase and a voice so sickly sweet that it could send a listener spiraling into a diabetic coma.
