Help me compile a list

[dbdartman]

I've admitted in the past that I'm not the brightest bulb on the X-mas tree. Also been accused of being a couple cans shy of a six pack.

 

[Farmwithjunk]

Not the brightest crayon in the box.

IQ X 2 still wouldn't equal a good fever

Good Evnin Jerry,
My Uncle Daves' favorite sayin is "He is dumber than a bag of rocks" Of course thats back woods Vt

 

[DocHeb]

Shoe size greater than IQ

Few pickles short of the proverbial barrel.

 

[Richard]

picking on an old collegue of mine, a guy born with a 'silver spoon' in his mouth, family VERY connected to old money and as an invesment advisor, he's simply clueless. Fortunatly for him, his father in law is keeping him afloat for the sake of the grandkids and his daugher (the wife).

"he's got all the ingredients but can't put the cake in the oven"

 

[Slacker]

He's about as sharp as a Q-Ball.

 

['Bota Fan]

Ain't got the sense God gave a goose.

And from "O Brother, Where Art Thou?", "You boys are 'bout as dumb as a sack of hammers."

 

[deere755]

One of my favorites is his or her biscuits aren't done.

His or her pilot light is out

His or her dogs aren't all barking

Not the sharpest pencil in the group

Doesn't have both oar's in the water

 

[TedLaRue]

"He's got muscles in his head that ain't never been used"

(from John Prine's song "That's the Way That the World Goes 'Round")

I know a guy that's got a lot to lose.
He's a pretty nice fellow but he's kind of confused.
He's got muscles in his head that ain't never been used.

['Bota Fan]

He's as free of thought as a turtle is of feathers.
