This question comes straight from a conversation that Abby and McGee have in the episode "Road Kill." From the episode:
ABBY: I'd pay to see the right battle. Like Leroy Jethro Gibbs versus...
ABBY: Oh, McGee, I was thinking like Terminator.
MCGEE: Which model? TX? T1000?
ABBY: All of them. Gibbs terminates.
MCGEE: Alright, how about Gibbs versus Godzilla?
ABBY: King of the monsters? Toast.
ABBY: Wingless in a nanosecond. Come on, McGee, give me something fierce. Boss-man's got mad skills.
