There was Commander Dante, Marneus Galgar, Ghazghkull Thraka, Commissar Yarrick and a guardsman who were travelling in a aero plane. Suddenly, the flight captain announced that the plane had begun crashing (he didn´t state why) and that the passengers had to jump off the plane with para-chutes. The problem was that there was only four chutes to the five passengers, so one had to be without.
Dante quickly got to his feet and announced as he was leader of one of the most famous Space Marine Chapters, he had to get a chute. He grabbed a chute and jumped out. Marneus got to his feet, saying the same. He did the same as Dante, grabbing a chute and jumping off the plane.
Now Ghazghkull got up and said, as he wasn´t only the most famous (or infamous) of Ork warlords through time, but also the galaxy´s smartest Ork, he had to get a chute. he grabbed a bag and disappeared.
Yarrick turned to the young guardsmen with a tired look in his single remaining eye, and said:
'My dear friend, I am an old man, and will sooner or later join the Emperor of Mankind beside him on his Golden Throne. Take the remaining parachute and save yourself.'
The guardsman just smiled and answered:
'No need to worry Commissar Yarrick, sir. You see, we both get a chute.'
'Why?' Yarrick queried.
'Why? The galaxy´s 'smartest' Ork just jumped off with my backpack.'
