If it's God, go circumcise your neighbor's baby and then offer it in a sacrifice, preferably in a fire. Chant some random garble and then sip the baby's blood from the Goblet of Coon. Oh wait, I forgot. Before you sacrifice the baby, drain it of it's blood into the Goblet of Coon. Find the mouse hole where he sleeps in, tie a piece of cheese to your "coin purse", and let it hang low and dangle outside the hole. When he bites, you'll know, and that's your chance to nab him.
