• I’m allergic to stupidity, so I break out in sarcasm

• A wise man never knows all, only stupid fools know everything

• The two most common elements in the universe are Hydrogen and stupidity

• Common sense is not a gift. It’s a punishment because you must deal with everyone who doesn’t have it

• Never argue with stupid people, they will drag you down to their level and then beat you with experience

• There is nothing more annoying than somebody who is stupid but who believes with absolute conviction that he is more intelligent than you

• “The Dunning Kruger Effect: Dumb and stupid people don’t know how dumb they are. They don’t even know how much stuff they don’t know. They don’t know that other people know the stuff they don’t know that they don’t know. Dumb people believe they know everything there is to know.”

• Wise men speak because they have something to say; fools because they have to say something

• The more you know, the dumber you sound to stupid people

• Wisdom doesn’t really come with age. A moron doesn’t become a wise man when he grows old; he becomes an old moron

• Technology is getting smarter and smarter: smartphones, smartwatches, smart homes… Only people remain stupid no matter what

• One thing that humbles me deeply is to see that human genius has its limits while human stupidity does not

• A clever person takes notice of everything; a stupid one makes a comment about everything

And finally, my best friend Ron White’s quote:
There’s not a pill you can take; there’s not a class you can go to. Stupid is forever. Ron White
