dumb as a stump
Extremely mentally slow
Dumb as a stump describes someone extremely stupid or slow-witted.
The comparison is to a tree stump—a thing with no brain, no capacity for thought, just inert wood.
He's dumb as a stump, but he means well.
The phrase is folksy and rural in flavor, often used with affection or resignation rather than malice.
