High swine

Came up with this one at lunch today, when my daughter thought it would be funny to throw a piglet out a window:

Pigs fly when you're having fun. 

Daily in the geological sense

I've been sharing these with my buddy Kevin rather than posting them here. But here's a few from the past couple years:

One trick dog and pony show.

An illegible recipe: made from chicken scratch

You gotta put your foot down if you want to get a leg up.

It takes a village idiot

Starry cross-eyed lovers (Kevin overheard on the radio)

Do unto others as you have done to yourself (Kev also heard on the radio)

Don't shoot until you see the whites of their eyes are bigger than their stomachs.

If you want it done right, do it unto others.

Overhead on NPR: "The 800 pound elephant in the room"

I just came up with this one: Speak of the devil in the details.

And on the radio the other day a guy said "we shouldn't paint with broad brushes."

Kevin used the expression "I dug a hole and now I have to sleep in it."

This made me think of "You shit where you eat, and now you have to sleep in it."

Sounds smooth

I was watching Good Will Hunting, and I heard the mixed metaphor "Keep your ear to the grindstone"

Flash mob

It takes a village to tango.

This Title Intentionally Left Blank

A few that I thought of recently:

Out of the pan and into the kettle black
On the bleeding edge of your seat
Raining teeth and nails

Pig in a jacket

I wanted to post a few I can't up with recently:
Don't judge a book until you've walked a mile in its dust jacket.
Squealing like a stuck pig in a poke.

Cutting through the hoops

Ciamh came up with a good one (accidentally I might add):
There's a lot of red tape to jump through

It's not over until the fat lady comes home to roost.

A snowball's chance of freezing hell over

Smooth Dreams

Last night I was really tired and said to my wife, "I'm going to sleep like a baby's bottom."
