A leopard never changes its spots.
A Skunk without stripes still stinks.
Back when he was knee high to a pup.
Busy as a Bee.
Crazy as a June Bug.
Don't be beating around the bush.
Don't be making mountains out of mole hills.
Don't be measuring my corn in your half bushel.
Don't jump from the frying pan into the fire.
Don't send a boy to do a man's job.
Dumber than a coal bucket.
Getting along like a herd of old turtles.
Got a chip on his shoulder.
He's a chip off the old block.
His bark is much worse than his bite.
It's your little red wagon now you pull it.
Just like two peas in a pod.
Keep your nose to the grindstone.
Like looking for a needle in a haystack.
Madder than an old wet hen.
Meaner than a striped snake.
Moves slower than molasses on a cold winter day.
Nervous as a long tail cat in a room full of rocking chairs.
One rotten apple can spoil the whole barrel.
Pretty as a speckled pup under a little red wagon.
Prouder than a peacock.
Puffed up like a stomped on toad frog.
She ain't no spring chicken.
She can waste more than three good men could ever carry in.
She's got a bee in her bonnet.
Slyer than any fox.
Snug as a bug in a rug.
Stubborner than a mule.
That'll knock your hat in the creek.
That's a horse of a different color.
That's the straw that broke the camel's back.
The acorn never falls far from the tree.
The battery on that old truck was dead as a door nail.
The grass always looks greener on the other side of the fence.
They can ask more questions than a Philadelphia lawyer.
They couldn't carry a tune in a bucket.
They worked me like a borrowed mule.
Tighter than the bark on a tree.
What's sauce for the goose is sauce for the gander.
When it rains it pours.
You can't believe a thing he says. He lies like a yeller dog.
You can't make a silk purse out of a sow's ear.
You can't saw sawdust.
You can't stack sawdust.
You could've knocked me over with a feather.
You made your bed now you're going to have to lie in it.
You're walking on thin ice.
You might have to eat them words.
