King Arthur was leaving Guinevere in care of Sir Lancelot while he left on extended buisness. He incased her nether regions with a stout chastity belt, entrusting the key to Sir Lancelot. After Arthur had proceeded a short distance down the road, Lancelot galloped up in a great hurry ""King Arthur!"" he exclaimed, ""You gave me the wrong key!"".

The Knights of the Round Table are sharing stories Sir Lancelot is speaking: So, dear sirs, I was fighting this dragon with three heads. I chopped one head off, it grew two more. I chopped two off, it grew two more. I chopped three off, it grew five more. I chopped one off, it grew none. I chopped one off, it grew three more. Sir Galahad interjects: So how did it end? Well, after chopping for half an hour, I still could see no pattern there.

Sir Lancelot was late to a meeting of The Round Table.. He was running down the corridor when he yells out to the guards: ""Hurry open the door!!!"" The guards didn't recognize him from such a distance, and reply: ""Pray might you be?!"" Lancelot responds: ""I am Authurized Personnel !""
