Can't tell his ass from a hole in the ground.
Can't tell his ass from his elbow.
Can't see the forest for the trees.
Can't see the wood for the trees.
Cares melt when you kneel in the garden.
A carrot on a stick.
The cat's meow.
Caught between a rock and a hard place.
Onions treat seven ailments.
Only the strong survive.
On middle ground.
Open up a can of worms.
Our neck of the woods.
Out with the old, in with the new.
Pin a rose on your nose.
A place in the sun.
Plain as water.
Plant kindness and gather love.
Play a harp before a cow.
Pull it up by the roots.
Put off the scent.
Put that in your pipe and smoke it.
Putting it in a nutshell.
Putting the cart before the horse.
Put to bed with a shovel.
