A lengthy game

"How long have they been at it?"
"Three and a half hours, General."
"Should I break it and decide for them?"
"No, sir, this is way too amusing."
"One has to accept any and every bit of entertainment one can get in these trying times, I suppose."
"Yes, sir."

An Earthling would be thoroughly amused that even a long time ago, in a galaxy far, far away, there still has been some kind of variation on 'Rock, Paper, Scissors'.
Watching two clone soldiers trying to decide who gets the first watch using this game, would certainly prove even more interesting.
