A/N: Three musketeers, I have no idea what the Naval Observatory looks like inside (nor do I care), I fully expected Tony to start singing "fly me to the moon" at one point while making a half-assed pass at Ziva, but that required more writing than I was willing to do (there will be many more cop-outs like this in this challenge)
McGee couldn't hide his excitement as he walked into the Naval Observatory hall. "Last time I went on a date, we came here and searched for Saturn, it was her favorite planet "
"Only you would find the one woman on planet earth who has a favorite planet," Tony said as he placed a numbered tag next to a shell casing on the floor and snapped a picture.
"There is nothing wrong or strange about having a favorite planet," Ziva said.
This piqued Tony's interest. "Do you have a favorite planet, Miss David?"
She let out a huff of air. "No."
Tony chuckled. "I bet you have a favorite knife, though."
"I do," she turned to face him. "And I am carrying it right now."
Tony looked her up and down briefly. "Well, keep it hidden..." He grinned, stepped into her personal space, and in a serious voice continued, "keep it safe."
Ziva rolled her eyes as he walked towards a discarded coffee cup while mumbling "my precious".
"That is not how the quote goes," she said, picking up the waste paper basket and inspecting the contents.
Tony stood up straight after placing another tag, and smiled widely. "Hey, McFrodo, Ziva watched Lord of the Rings."
Ziva didn't bother to look up from the shredded paper she was holding. "No, I read the books."
"Oh, I love the books," McGee said, before crouching down to look underneath the desk.
Tony wrinkled his nose. "I bet you two are really boring at dates."
"You think I would be boring?" Ziva said into his ear, making him jump.
"Boring like a heart attack." He loosened his tie, as she prowled around him with a sly smile on her face.
"Miss Saturn didn't think I was boring," McGee said cheerfully, standing up again.
"I bet the magnification of her glasses rivals the observatory's telescope."
"Actually, Miss Saturn was last year's runner up in the Miss Washington pageant."
Tony's eyes went wide. "Really?"
McGee nodded gleefully.
"When's the wedding?"
"We broke up a few weeks ago."
Tony grabbed McGee's upper arms, and said, "What's wrong with you?"
McGee rolled his eyes. "She didn't like video games."
Tony removed his hands as if burnt. " She didn't like...psh!" He looked at Ziva in disbelief.
"You seem agitated, Tony," Ziva said as she looked up at him sweetly "Too much coffee? Or perhaps not enough dating?"
He pursed his lips and stared her down. "There is nothing wrong with my dating."
Ziva shrugged. "If there is, you could always ask McGee for dating advice."
