I like George Carlin's quote : Never underestimate the power of stupid people in large groups.

i know an oldie but a goodie if you're looking for insults, appearance wise; "you're a thief and a murderer; you killed a monkey and stole his face"

I like ''Your elevator doesn't quite go all the way to the top, does it?''

My personal favorite is “I expect nothing from you, and yet you never fail to disappoint me.”

Well my father once told me when I was 12 I did something stupid and he said "you make me f*****g wonder sometimes boy that I should've shot you on the sheets" never knew what that meant until I was a man

Just heard a good one: "I could eat a dictionary and crap out more sense than you make"

One of my favourits is a quote from Blackadder the third: "Your brain for example, is so minute, Baldrick, that if a hungry cannibal cracked your head open, there wouldn't be enough to cover a small water biscuit."

If you had a brain, you'd be on the floor playing with it.

One of my favourites:- If he had a brain cell it would die of loneliness.

Unfortunately, I don't know any other good ones for intelligence, but I once heard someone refer to an unattractive person as having, "a face that takes some getting used to", and I still smile when I think about it.

He must have gone to university for stupidity. It must take a lot of talent to be that thick !

Reminds me of the brilliant book: never play leapfrog with a unicorn (https://ontheroadbooks.co.za/products/never-play-leapfrog-with-a-unicorn-arthur-goldstuck-and-william-ramwell). So many brilliant insults in that book like: has his solar panels pointed at the moon.

My brother used to say, “If your brains were gas, you wouldn’t have enough sense to drive a pissant’s motorcycle half a lap around a Cheerio.”

My favorite: If you were any dumber you’d have to watered twice a day.

Scott "Dilbert" Adams once remarked that the world is full of 6 billion idiots. But because they outnumber the rest of us, we don't call them idiots to their face. Instead we say "In-DUH-viduals."

My personal favourites are... If your brains were made of chocolate you wouldn't have enough to fill a Smartie (UK)! And You are proof that light is faster than sound. You look bright until you open your mouth. Then there's, So stupid he could not spell A and So dumb he would count his fingers on both hands twice and come up with 11 and 9. Finally, there's: So stupid he has his name written in his underwear, so he does not forget who he is

My favorite comes from the play Cyrano De Bergerac. "These, my dear sir, are things you might have said, had you some tinge of letters or of wit to color your discourse. But wit? Not so, you never had an atom. And of letters, you need but three to write you down: A, S, S. Ass!"

OMG, I WAS AT CAPE DISAPPOINTMENT YESTERDAY! <3

i love these! i'll have to remember them for when people are annoying me

The bar was so low it was in hell but you just played limbo with the devil.

The lights are on but no one's home

I love these! Thank you BP.

Well good sir and/or madam I care not to trade insult with inferior being.

Dumber than a bag of hammers, window licker, crayon eater, mouth breather. Just a few off the top of my head I've heard and used.

There's wiser eating grass

I always say "such a genius with a j" because this sort of misspelling is very common in my country.
