The Elephant Headed God

Listen here, numbskull. The joke is that the question implies a search for the "true" God, but the punchline reveals that the elephant-headed God is considered the true God because he doesn't exist. It's sarcastic and a bit dark, kinda like your chances of understanding this without me, Explain Bear, spelling it out for ya. You're probably the kinda guy who thinks the Earth is flat, ain't ya?
