Here's (above) the classic dumbell design favored by Tex Avery. It works great.
IMO Clampett's version of dumb is even better. He always adds some other trait to the stupidity. Like Clampett's Beaky Buzzard: he's dumb but he thinks he's smart.
That long, deliberately awkward neck allows for some great poses.
When humans try to do what Beaky does (above) it doesn't look right. The girl above looks pitiable rather than funny.
According to the chart above, Beaky's "S" shaped torso is actually a deformity. It's called "Thoracic Kyphosis."
This cat (above) from Clampett's "Kitty Kornered" has a different ailment: Lumbar Lordosis!
You could argue that Donald has a pear-shaped body because he's a duck, but what's Mickey's excuse? Lumbar Lordosis strikes again! Goofy appears to have Thoracic Kyphosis accompanied by Buckle Leg.
Knock kneed and bow legged characters abound in animation. Sometimes they walk almost normal then settle into their deformity when they relax in place.
Not all unusual alignments are problematic. Here (above) Tex's wolf shows a waist that's situated high, immediately under his rib cage. It works...in fact it looks good.
Here's (above) proof that Tex didn't make up the rib cage waist. Some people bend that way.
