They left Lucky Charms and Irish Spring soap and buttons and cards and coins, and put a chair up on the center island.

They put my flip flops in the fridge.

They tied Big Kid's backpack to a chair with toilet paper.

They filled the sink with green easter grass and stuck the boys' toothbrushes to the mirror.

They barricaded the boys' door with pool noodles.

They blocked the front door with chairs. (I guess those sneaky little bastards aren't familiar with fire safety violations!) And they dyed our milk green.

little kid is furious.
He can't be convinced that this was all in good fun. He thinks this was an adversarial move on their part and he will seek vengeance.
He stomped around with his hands on his hips inspecting their work. "Your shoes are in our 'frigerator? That's it! I'm gonna catch that lepocon and beat his brass for this!"
"What did you say? You're going to beat his what?"
"Nuffing."
"Good."
Eventually the story began to evolve.
"I saw 'em. I saw the lepocons."
"Oh yeah?"
"No you didn't!" yelled Big Kid.
"Yep. He was gween."
"It was probably a black man," Big Kid speculated. (wtf, Big Kid?)
"No, he was gween."
"Was he wearing a hat?"
"Yes."
"A green top hat with a belt around it and a buckle?"
"Yep."
"Did he have a beard?"
"Yep."
"An orange one?"
"Yep."
"Was he real short?"
"Yep."
"Mom, I think he really saw a leprechaun! Man, I wish I saw the leprechauns."
"There was lots of 'em. They was havin' a party, IN OUR HOUSE! I caught one wif a net but he got away. Next year I'm gonna get one and keep him! But I gonna need some help with 'at, k mumum?"
little kid is also convinced they stole some of our bananas and he's angry about the mess made with the easter grass. He found a small hole in the screen door and he's pretty sure that's how they got in. "Our first clue!" he shouted.
He will begrudgingly admit that it was nice that they left M&Ms, but they'd better watch their brasses next year.

Happy St. Patrick's Day!
