As they say, "the lights are on but nobody's home". Sad.
The elevator does not go to the top floor
The train is running, but the engineer is asleep at the wheel
A few fries short of a Happy Meal
Her sewing machine has no thread
A few beers short of a six pack
She has a hole in her marble bag
She's one putt short of par
She's as smart as bait
Her chimney's clogged
There's no grain in her silo
Dumb as a box of painted rocks.
