Thomas Grace: Don't ever do that spinning kung fu crap. You'll get yourself killed.
Rachel Gibson: Okay, fine. What should I be doing?
Thomas Grace: Go for the eyes, the throat, the nuts!
Rachel Gibson: The nuts? Wha...
Thomas Grace: Cause as much damage, inflict as much pain as humanly possible!

Kelly Peyton: You bitch! You should've given me the disc.
Rachel Gibson: You were gonna kill me, anyway.
Kelly Peyton: Yeah... but I would've felt bad about it. Now it's gonna be fun...

Rachel: Your father's kinda scary.
Sydney: Tell me about it.

Marshall: Listen, I’ve had to do a little alias magic myself to save the day a few times. Do you know what a spork is?

In this particular case Marshall is referring to the episode 4x13 "Tuesday"
where he went into the field as Jack Bristow to retrieve a hard drive. The spork he mentioned he used it to cut out a man's eye that he needed for a biometric scanner.
