Hagar

A prisoner who was about to be executed by firing squad was asked by the captain if he had a last request.
Prisoner: "Can I have a nicotine patch?"
Captain: "An unsual request! Won't you rather have a last smoke?"
Prisoner: "No, I gave up smoking last month."
Captain: "Well, I'll have to ask the Colonel." [Exits]
[Captain returns]
Captain: "Sorry, the Colonel says regulations prevent us from giving you a nicotine patch."
Prisoner: "What regulations?"
Captain: "They were drawn up by the General who is a Computer Science graduate trained in the best of software engineering practice; his professors taught him the dictum Never Patch The Executable."
