OK, that's not the weirdest thing God has ever told someone to do. Plus it tastes like honey. So far, so good. Then God tells Zeke to construct a little scale model of Jerusalem out of clay, and stomp the crap out of it like a bully wrecking a sand castle. This is, we guess, the less subtle part of the prophecy.
Then God just wants to see how far he will go. He tells Ezekiel to lie down on his left side and stay there for 390 days. Then he's allowed to roll over -- presumably with one hell of a cramp and a bad case of bed sores -- but he has to lie on his right side for another 40 days, pointing at the squashed remains of the Jerusalem model the whole time so that people really get the message.
Future artists would be less subtle.
God, snickering, just cannot believe he's doing all this, so he really ups the game: The entire time, Ezekiel is allowed to eat nothing but bread that he cooked on a bonfire of human poop. This is the part of the prank show where most victims would start looking around for hidden cameras, but not Ezekiel. He just stoically bargains God down to cow poop instead and mistakenly calls it a victory.
