Rule #21: Rule 20 applies to Abby also.

In a moment of light-hearted fun, Tony is aiming for the back of McGee's head, narrowly misses, and hits Abby instead.

Kittens begin weeping.

THREE MONTHS LATER:

The combined tears of all kittens create a second world-wide flood, as Abby follows Tony around, asking, "Why, Tony? Why?"

Rule #22: The ultimate purpose for a credit card is becoming a weapon in Ziva's hands.

Ziva, in evening gown and stilettos, corners bad dude, holding only a purse

Bad dude: Whatcha gonna do, kill me with a credit card. (Laughs uproariously, thinking he is a wit.)

Ziva opens her mouth, pauses, smiles, then proceeds to stun and incapacitate him using only a credit card and her left elbow.

Rule #22: Never, ever bother Gibbs in interrogation. Ever. This is too serious to parody.

NB: The author attempted to discover what would happen by actually bothering Gibbs in interrogation. We are not sure exactly what happened, but we are happy to inform you that she is out of ICU and the prognosis for full recovery is good.

Rule #23: Never mess with a Marine's coffee if you want to live free of debilitating injury and/or complete misery.

Coincidentally, the method by which she tried to bother Gibbs involved stealing his coffee.

Rule #24: When you need to be given quick and simple information, don't ask Ducky.

Tony: Hey Ducky, are those bloodstains shaped like fish?

Ducky: Well, it's interesting you should mention that. You see, if what we are seeing here is real, then this is very much like an autopsy I performed when…

Rule #25: If you break 24 and ask Ducky, DO NOT tell him his stories are boring and you don't care.

Tony: *tied to a chair, totally exhausted, eyes glazed*

Ducky: And then my father took my out on a boat and taught me how to fish. Very interesting, eh?
