Seriously bro, NEVER bake dirt in your oven. The smell will make your entire house un-inhabitable for days, and your place will smell like flaming horse crap for weeks!
I cannot stress this enough, Dirt + Heat = rotting corpse/burning horse crap stink that will fill your house with evil spirits, tormented souls, and demonic voices crying out in anguish!
Never put dirt in your oven. Its bad enough when you sterilize infected dirt over an open fire in your back yard (cops still got called on me) but your oven will smell like burning garbage forevermore. Your old lady WILL leave you, your landlord WILL evict you, and the cops WILL get summoned to your house!
