"If I have to remove one more paper aeroplane from my hair, Tony, you are going to lose one of your appendages. And trust me, it will be one that you will miss dearly," Ziva growls.
It's been three days & no new cases have come up. Gibbes has escorted the Director to a meeting in New York & McGee has been spending his free time down at Abby's lab playing video games.
"Play Twenty Questions with me & I won't have to resort to such immature entertainment," Tony replies with a smirk.
"Fine." Ziva swings around in her chair as Tony whoops with joy. "OK, I'm thinking of an object. Ask your first question."
"Is it in this room?" Ziva asks. But Tony isn't listening. His eyes are fixed on McGee's desk. The attention span of a goldfish, Ziva thinks.
"Ziva, there are only two reasons why Probie would have a lock on his desk drawer. One: it contains confidential documents. But he's Probie, so anything he knows, I already knew ages ago. Two: he's got something so good in there he can't trust his fellow workmates to keep their sticky fingers off of it."

With a gleefully mischievous grin on his face, Tony takes his lock picks & heads towards McGee's desk.
This could be trouble, Ziva thinks. But at least if Tony gets busted it will be entertaining.
"Curiosity killed the rat, Tony. Remember that." Ziva warns.
"It's cat, Ziva. Curiosity killed the cat." Tony corrects her.
After a minute of picking, the lock pops open & Tony slides out the desk drawer.
"I will have no part of this." Ziva turns her back, but listens intently to Tony's rummaging.
"Comic books, a video game, gum, pencils… Come on McGee, where are the Playboys?" The rummaging abruptly stopped.

"Oh. My. God."

Ziva swings her chair around with such force that it almost spins out of control. She jumps up & tries to disguise her stumble. "What has your snooping uncovered, Tony?"
With his mouth hanging open & his eyes wide, Tony turns to face Ziva, holding a pair of pink, lacy panties.
"I think your probing of Probie's personal property has revealed a whole new side to our sweet little McGee." Ziva grins.
"Please don't tell me that McGee has a secret office romance going on. That's not fair!" Tony exclaims.
"Maybe not. Maybe they're his. He does seem like quite a – how do you say – effeminate man?"
"Oh, Ziva, please don't put that image in my head! I'm only just getting over the nightmares of Ducky's voyeur adventures from the sixties!"
"Well, I can't imagine why McGee would have women's panties in his desk drawer."
"I think I have a good idea. The 'cute', shy guy attitude is just a cover. He's really an insatiable sex fiend. He's probably doing every chick in this office-"
"Well he's certainly not 'doing' me, Dinozzo," Ziva cuts in.
"Of course not, Ziva. No one in this team considers you a chick – ah, I, um, I mean we all consider you a woman, not a chick." Tony quickly corrects himself as Ziva gives him a chilling death stare.

Just then, Abby's voice drifts through the room. "You must spend hours playing at home to be that good at Xbox, McGee."
"You're on your own, Dinozzo," Ziva whispers as she races back to her desk. She quickly starts typing away with her down head, stifling her laughter.
Tony shoves the panties back into the drawer & slams it shut, hearing the lock click back into place. He dashes back to his desk & plunges into his seat, making a poor attempt at sitting casually with his legs splayed in front of him & his arms behind his head.
A split second later McGee & Abby round the corner & approach McGee's desk.
"Hi Tony, Ziva. Tony, why are you panting?" McGee asks, furrowing his brow.
Tony gives a big, cheesy grin & replies, "Exercise. I just finished fifty laps of the office. Some of us Senior Field Officers have to keep in shape for the sake of our job, McGee. Not all of us have the luxury of getting soft around the middle like you."
Ziva stifles a snort of laughter & lowers her head, pretending to work hard.
Abby pipes up, "Don't you listen to him, McGee. Soft & pudgy around the middle is the best way to be." She gives him a playful squeeze around the middle. "Well, Ducky just gave me some tissue samples to process, so at least one of us has work to do." She turns & heads back to her lab.
Tony turns & begins to shuffle documents on his desk. He looks up to see Ziva grinning cheekily. He suppresses the urge to burst out laughing and then shudders as images of McGee in lacy pink underwear enter his mind.

McGee sits at his desk & unwraps his lunch, oblivious to the recent events surrounding his Locked Drawer of Mystery, which Tony wishes had remained mysterious.
