Disable A User

We were in a meeting yesterday when a manager said we need to be able to disable a user. Actually, his sentence may have continued with more details, but my mind was already thinking about this comic. I did not decide how to end if until this morning. All my notes said were "disable user. hit him in knee with pipe. he meant in system." Once I began creating the strip, I decided to try and think of some way to use kill in the final panel, and then I knew what I wanted Mr. Green to say.
