Materials Needed: Pen or pencil, paper
Object: Guess what your cellmate drew.
Game Play: On a piece of paper, have your companion draw a square. While you avert your eyes, they look around the chapel and find some small insignificant detail to draw inside the square, in close-up (the more obscure, the better). It has to be an object that both of you can see. When they're done drawing, they give the paper to you and you have to figure out what the object is. (In the example below, it's a close-up of the hymn number easel in front of the chapel. What, you couldn't tell?)
You may think this game is a little boring and might get old quick. You are right. But we were bored, man!
If you don't guess it, your cellmate gets a point. If the game gets just too darn easy, apply a time limit. If your cellmate can't draw worth a dang, try the next game.
