AN: Prank idea is from LilDevyl. Thank you very much!

Not everyone was an early bird, but for this particular prank Ryan and Cooper had managed to get together the day shift and night shift CSIs, patrol officers and several homicide detectives. With permission from the Chief they had decided to pull one hell of a prank on Horatio and Frank. Therefore they were all in the lab, waiting for Cooper and Ryan's instructions.

"Okay listen up people!" Ryan said, "Cooper and I have photographed every inch from every angle of Lt. Caine and Srgt. Tripp's offices; the idea is that with help from the photos we're going to change Horatio's office into Frank's and the other way."

Everyone laughed and was divided into two groups. One group would go to Frank's office (he had recently got a glass office like Horatio) and the other to Horatio's. They grabbed the photos Cooper had in his hands and started working. Cooper joined the "Tripp- group" as they call themselves and went down to the homicide department, while Ryan went with the other group.

They had three hours to finish the prank and then leave and come back to pretend that they had just arrived. It took a little more than two hours before they were done and someone shouted that Horatio was on his way up to the lab. Everyone had been smart enough to park their cars somewhere else and not in the department parking lot, so Horatio didn't notice anything different when he arrived for work. Panic spread through the lab and the homicide department as the elevator started moving with the red head inside.

"Hurry! Use the stairs!" Calleigh exclaimed and everyone (over 60 people) ran to the stairs and went down just as Horatio arrived at the lab and Frank drove in to his parking space.

Horatio read a file as he walked to his office and opened the door. He gasped; it wasn't his chair, his desk, his couch, not his files or computer, it wasn't even his door that he had opened! He dropped the files he was holding on the floor in shock and he walked further inside and looked around. His pencils were gone, his photo frames; everything! Everything he had had in his office when he had left the night before was gone!

In the meantime Frank whistled and smiled as he approached his new office; it felt good having an office instead of a cubicle. He opened the door and… it wasn't his desk, his chair, his couch, his pencils, his computer or even his door! Everything was gone!

"What the, I mean… Who… how?" He said in pure shock as he approached his desk.

He stood there staring at what used to be the place where all of his things used to be as his co-workers arrived for work; they chuckled and went to his office.

"Did you re-decorate?" They asked innocently.

"No!" Frank growled, "I don't know what happened. Who could have done this? It has to be Cooper and Ryan, but they couldn't have done it alone. Ryan is smart enough to pull something like this off, but neither he nor Cooper got the muscles to carry everything away."

"They must have had help." One detective said and bit the inside of his cheek to keep from laughing.

Meanwhile Horatio growled as he entered the break room, making his team look at him innocently.

"Who was it?" He asked, "I'm guessing Cooper and Ryan did this, but neither of you are strong enough to carry all of my stuff out and replace it with someone else's."

"I'm strong!" Cooper whined.

"You have less muscles than a 10-year-old girl." Eric snorted, "They must have had help, H."

"And I want to know from whom." Horatio growled.

Ryan and Cooper shrugged and their boss growled before leaving. He went to the surveillance room and got there on the same time as Frank.

"Something wrong Francis?" Horatio asked.

"Somebody re-decorated my office." Frank growled.

"Mine too."

They looked at each for a while.

"Do you have a pencil with a… pink feather on it?" Horatio asked.

Frank rolled his eyes, "It was a gift from my daughter; she said pink would be good for my bad mood in the mornings. Does your couch have two green pillows with Homer from The Simpsons on it?"

Horatio blushed, "It was a gift from Calleigh; she said it would make me smile more."

"They switched our offices." Frank growled, "Now we find out how they did it."

They entered the room and looked at the surveillance tape. Their eyes widened as they realized that they were working with a bunch of "traitors."

"Those, those… those…" Frank said.

"How did they manage to organize all of it?" Horatio growled, "One thing is for sure; if everyone helped them, we make them help us too."
