Orr shares a tent with Yossarian, and is very mechanically adept, as he manages to make for them the most luxurious tent in the squadron. When working on small pieces for an oven stove in the tent, Yossarian sees his work as arduous and highly unnecessary as the pieces are too small for anything of real concern, yet at the end while using his stove, he realizes the intricate simplicity of improving the stove's performance. Although this tinkering drives Yossarian mad, any idea of harming Orr is so absurd that Yossarian can't follow through with it.
