Towards the end of Konami's Metal Gear Solid 2 (PS2), a computer AI operating under the alias of Colonel Campbell becomes infected with a computer virus codenamed "GW." The virus proceeds to scramble the AI's memory and logic, causing the AI Campbell imposter to utter numerous phrases of complete nonsense, among them the phrase "...I need scissors! 61!" It is part of a longer quote, listed below.

The phrase "I need scissors!" has no particular or coherent meaning, as it is simply the product of a horribly scrambled AI.
"I hear its amazing when the famous purple stuffed worm in flap-jaw space with the tuning fork does a raw blink on Hari Kiri Rock. I need scissors! 61!"
