When I was first helping a buddy get into 40k, I gave him half of my Assault on Black Reach box. He was curious about the orks, and since neither of us had a codex yet, I told him, "Imagine you're an Imperial Guardsman, shooting at an oncoming ork. He shoots at you continually as he charges in, and you only manage to drop him as he's about five feet away. In doing so, you run out of ammo for your trusty lasgun. Seeing another charging ork, you quickly ****** up the fallen ork's slugga and point it at the other ork. You pull the trigger. Click. Nothing. You check the gun. It's a cardboard box! With a handle and a hole in the end! The clip has a bunch of crayons in it! HE WAS JUST SHOOTING YOU WITH THIS GUN, AND HE WAS LOADING CRAYONS! The new ork back-hands you and picks up that gun you were just holding. "Glad you killed 'im, ya stinking 'umie, I sure wanted 'is slugga! It's right killiy!" And shoots you. With crayons.
