Did anyone manage to see NCIS between 'treaters last night? What a riot!
McGee is sent in to process the scene, putting down the little numbers etc... He gets a feeling someone else is in the room and whirls around to realize that "someone" has picked up the bullet casings that had been lying on the floor and tried to wipe up the blood.
The whole team comes in and searches the whole house, no one is there. McGee looks like a fool.
Then Tony feels something brush against his foot and thinks he saw it disappear under the couch. He peers under the couch and jumps back with a yelp when something moves.
Everyone stares at the couch and.... out comes the ROOMBA!
Of course McGee has to explain it to the boss, and sexy curmudgeon that he is Jethro stomps on the machine and breaks it apart. With a look of disgusted surprise he states, "the vacuum cleaner policed the brass."
The have SCOOBAs now too. The killer could vacuum and scrub the whole house after a murder without even being there. And the best part is, unlike in NCIS, you could have the little robots back in their chargers by the time anyone discovers the body and maybe no one would think to look in the vacuum cleaner for evidence!
