Chapter 3

When Tim came back he passed Tony's desk and noticed he was writing lines.

"What ya do?" he asked.

"Nothing." Tony said with a snarl. "I did absolutely nothing. Someone must have messed with my cell, but I haven't had time to look at it, Gibbs is pissed, he already took to me with a ruler, I have to get these stupid lines finished before he gets back from interrogation."

"Throw me your phone and I'll have a look at it for you." Tim said. Tony passed him his cell and went on with the lines. "So what made Gibbs so pissed anyway?"

"He was in interrogation........ every time I tried to call someone, it went to Gibbs cell. The final straw was when I thought I was talking to you and happened to call you a moron for not answering your phone and the Boss thought I was talking to him.

"OUCH!"

"Yeah OUCH!"

After Tony's explanation, Tim had a fairly good idea what had happened. He started to go through the numbers on the cell.

Ziva's heart was thumping in her chest as Tim scrolled through Tony's cell phone. She did her absolute best to keep the emotion off her face. Luckily, Ziva did a straight face very well. It was also lucky that Abby was not here. She did NOT do a straight face very well, Ziva thought.

"Ok. Tony. Here's your problem." Tim said as he walked towards Tony's desk. "All your speed dial numbers are set to Gibbs number." Tony shook his head.

"And who would do a thing like that?" he said looking directly at Ziva.

"I don't know Tony. Do you still have that list of enemies that you had to compile that time?"Ziva said sarcastically.

"Very funny Ziva." He said narrowing his eyes at her suspiciously.

"Are you inferring that it was me Tony?" Ziva asked.

"No. I'm not inferring anything. BUT, I'm telling you this Zi-va Da-vid, that who ever did do this, had better watch out!" he said as he finished up his lines and put the sheet on Gibbs desk. Taking a wary look at Ziva he gathered the lines back up and took them over to the laminator, and while he made sure that the sheets could not be altered by covering them in the plastic he mumbled to himself about dire retribution and revenge. When he was finished, he took them over to McGee's desk. "Would you mind these please McTrustworthy and give them to the Boss when he comes back?"

"Sure thing Tony." Tim said.

The girls laid low for the rest of the day, but by the next morning, Abby was all fired up and ready to go.

"Who is your next victim Abby?" Ziva asked.

"Well, I already did Jimmy and we need to give Tony a break today, so mine will have to be Timmy. Which is a challenge. He knows me so well, I have to be sure not to be too obvious."

"Thoughts on your prank?" Ziva said.

"Mmmmm." Abby said as she once again brought ideas up on the screen. "Oh yes!" Abby said as she found the perfect idea for Timmy. Ziva read over her shoulder.

"Is it dangerous Abby?"

"Na! Not if I don't use too much." She said grinning from ear to ear with excitement. The fact that her latest prank involved a bit of science made it even more exhilerating.

"I hope you know what you are doing." Ziva said as she went back up to the bullpen.

"Can you let me know when he and Tony aren't in the bullpen?" Abby asked as she started to get things out of her fridge.

"Sure." Ziva said with a smile.

Ziva bided her time waiting for Tony and Tim and Gibbs to be out of the office together. Gibbs was in MTAC and the perfect opportunity came when he leant over the balcony and asked the boys to join him for a moment. Ziva put in the call to Abby who was there in a flash. Abby had taken the end cap of a Bic pen and added a small amount of water and a tiny amount of Calcium metal. She ran up to the bullpen not bothering to wait for the elevator. She quickly took all of Tim's pens out of his desk and placed the doctored one where he could easily find it. Ziva was keeping watch. She hissed "Abby," as she saw the others leaving MTAC. Abby scooted into the hallway where she could watch without being seen.

Gibbs, Tony and Tim sat at their desks and immediately began following up whatever it was they'd been discussing upstairs. Tim got up to give something to Tony, and looked up to find Gibbs, who was on the phone, motioning to him for a pen. Much to Abby and Zivas horror, he leaned over to his own desk and passed Gibbs the dreaded pen. Abby was conflicted. Should she come clean, should she run over and snatch it off him and run down to the lab or should.........Too late.

There was an enormous bang right on the desk in front of Gibbs. So loud that in fact made him jolt back in shock effectively tipping him from his chair. If it was anybody else, it may have been funny, but the sight of Leroy Jethro Gibbs with his feet in the air after falling off his chair, the cause of which was a prank that she herself had instigated, was not that funny. Especially considering the fact that his feet had now moved, which meant that he was on his way back up. Not to mention that when his furiously red face did appear, it was covered in splatters of blue ink from the exploding pen. But even though it wasn't that funny, Abby had to clap both her hands over her mouth to keep from giggling. The smile left her face though as she saw him charging towards Tim. "Uh OH!" she said to the empty hallway. Gibbs grabbed Tim by the ear in much the same way as he had Tony the day before and bent him over the desk. Again, he picked up the only thing that was at his disposal, the dreaded ruler. He slammed it down over and over on Tim's backside while Tony looked on in horror and Ziva kept her head down. Abby stood in the hallway with hands covering her face. Poor Timmy. Poor her. Timmy was gonna kill her. So might Gibbs if Timmy told on her. So much for not being too obvious, it wasn't gonna take a genius to figure out who would know how to make an exploding pen.
