A/N: Here's the last chapter. Please review, but keep it nice.

Grissom hadn't been planning another joke but when he was rinsing out his coffee mug with the hose from the sink he got the greatest idea, and all he needed was a rubber band. He walked back to his office and grabbed a rubber band from the desk.

'Perfect,' he thought, 'Nick and Warrick are out in the field, and Greg's busy with Catherine on a case.' He slipped the rubber band tightly around the trigger and aimed the nozzle at himself. He smiled and got back to the work he had been doing in his office.

"Hey, Greg," Catherine said looking up from a stack of letters. "I'm going to go get a cup of tea, be right back."

He nodded and continued working.

Catherine strode down the hallway to the break room. Grabbing a mug from the cabinet she went to the sink. She turned on the water and instead of it coming out of the faucet it came straight out of the hose and on to her cherry red T-shirt. She quickly shut the water off but not before she got completely soaked.

'That's it!' she thought, slamming down the mug and taking off in search of Grissom, who she found in trace talking to Hodges.

"Grissom!" she yelled, despite the fact that he was only standing four feet away from her.

He turned to look at her and judging by the water on her shirt he was in trouble.

"Is this your idea of a joke?" she asked, her voice still muchlouder than necessary.

"It wasn't supposed…" She glared at him and Grissom decided it was better justto be quiet.

Catherine turned her glare to Hodges. "What are you looking at?" she snarled.

Hodges let out a cat like hiss and returned his attention to his microscope.

"Look Catherine, I'm," Grissom began.

"Forget about it," she said and went to change into her spare shirt.

After she changed she went back to where she had been working with Greg. He glanced up at her.

"Where's the tea? And weren't you wearing a different shirt?"

"Don't ask. Hey, you helped Sara with that one gag, right?" she asked.

"Yeh." He said, and then added, "How'd you know about that?"

"Give me some credit. Anyway, I need a plan to teach both of them a lesson and possibly do something about the sexual tension between them." He gave her a confused look. "Oh come on like you don't see it?"

"What do you have in mind?" he asked with a smile.
Shortly after shift ended the next night Catherine went in search of Sara while Greg went to find Grissom. Their plan was in action.

"Hey, Sara can you meet me in front of the locker room in 15?"

"Uh, I 'm kind of busy, what do you need?" Sara asked, looking up from her table.

"Shifts over you know?" Catherine reminded her. "Locker room, 15 minutes," she said and left before Sara had a chance to protest.

She went in search of Greg, hoping he'd had luck with convincing Grissom.

"Hey how'd it go?" Catherine asked Greg once she found him.

"Great, you?"

"I told her, and knowing Sara she'll be curious and come. How'd you get Grissom to agree?" she asked, realizing that Grissom would needsome sort ofexplanation.

"I told him that I found a bug in my apartment that I couldn't identify and I had it in my locker. You should have seen his eyes," Greg explained.

"Bugs," Catherine said and rolled her eyes. "Good thinking."

"Now what do we do?" Greg wondered.

"Now, we wait," Catherine said.

They both took seats on the benches in the locker room and watched the clock, willing it to move faster. Sara and Grissom still hadn't showed upafter 15 minutes had passed.

"You really think this is going to work?" Greg asked, getting impatient.

"It has to," Catherine said with determination. "Just give it time."

After waiting a total of 25 minutes Catherine spotted Grissom walking towards them from the left and Sara coming from the right.

"You ready?" Catherine asked Greg.

"You betcha."

Grissom and Sara reached the locker room at the same time, both taking one more step they both suddenly lost their balance, arms flailing, and reaching for something to hang on to. They both fell clumsily, Sara landing close to Grissom. She quickly pushed herself away and looked down at her hand.

"What is this?" Sara asked Grissom.

"Some kind of clear oil," he said. Standing up carefully he offered Sara his hand. She took it and came up way to fast, knocking into Grissom's body and holding onto his arms so they both didn't end up on the floor again.

"Now," Catherine whispered to Greg, who pulled a string and released four pillows full of goose feathers over Sara and Grissom's heads.

Sara's arms flew into the air, trying to avoid to white fluff. Her efforts having the opposite effect she ended up covered in them. When the feathers stopped falling Grissom, who was slightly less covered, took a glance at Sara and actually started laughing.

"You look like a chicken," he said, suppressing a laugh.

Sara let out a fake laugh, smiled sweetly and shoved Grissom back down into the oil. She looked down at him and started laughing for real. But ever so slyly Grissom grabbed her hand and pulled her back down. She landed right next to him once again and this time didn't make an effort to move right away.

"You've got a feather right…" she plucked a feather out of his hair. "There." She smiled.

He laughed and knew that wasn't the only feather that was on him. He leaned up and tried to push himself off the floor but ended up face to face with Sara instead. He looked into her eyes and saw the funny person she was shining through her rough exterior. He put a hand softly on her cheek and kissed her.

Catherine and Greg watched the success of their plan from just inside the locker room.

"And we didn't even need the third part," Greg mused.

Once Sara and Grissom separated and managed to get up safely Catherine and Greg got up and stood in the doorway.

"Have you two learned your lesson yet?" Catherine asked with a smile.

Grissom and Sara glanced at each other and then stared back at Catherine and Greg in disbelief.

THE END!
