6. Lie down on your side for one year, and eat bread baked with human poo!

God tells Ezekiel that in memorial of the siege of Jerusalem, he needs to build a model of the city. Then he needs to lie down on his left side for 390 days, then his right side for 40 days. During this time he is only allowed to eat bread which he has baked over a fire of human shit.

Ezekiel protests at this last bit, so God lets him use cow shit instead.

From Ezekiel 1:1-16.
