"Narf... what is: Narf?" A question that has puzzled many over the years. Narf is like Poit or Zort, but different. It is an exclamation of awe, sadness, pain, and happiness, among other things.
The phrase "Narf" is a favorite quote of Pinky, he uses it almost all the time, once it almost killed him and the Brain when Brain had Pinky change the Call-Sign of the Alvin (DSV-2), which Pinky changed from W-H-O-I (Woods Hole Oceanographic Institution) to N-A-R-F, which was misinterpreted by The Pentagon as a N-A-R-F (Nuclear Attack Readiness Formation).
