Just had an NCIS daydream: 

So we’re in an empty bullpen, 6:50 am in the morning, the elevator dings and DiNozzo Sr. walks in. As soon as he gets to the desks he notices a man … probably around his same age sitting at Ziva’s desk. They look at each other in an odd way and exchange a simple “hello” while Sr. seats at Tony’s desk.

They stare at each other for 20/30 seconds clearly trying to figure out who the other is, until the man at Ziva’s desk gets up and walks to Tony’s desk introducing himself:

“Eli David”

Sr.’s face lights up and he almost screams: “YOU’RE ZIVA’S FATHER!!!”

Than he makes a weird comment about Ziva’s “physical assets” and Eli looks at him with the it’s-my-daughter-you’re-talking-about look and they start talking about their “kids” until they’re interrupted by said “kids” who walk in the bullpen bickering bout something. They look at the two men, stop dead in their tracks and say at the same time “Dad(tony)/Father(ziva) … what are you doing here!?” *phoof* *opening*
