Rich
On your roof is a scarecrow because you're rich. You want to scare away all the poor, non-rich people so you put a scarecrow on your roof.
Imagine looking up at the roof at this scarecrow. There's a sign around its neck that says, "Rich people welcome." Ah, you're safe. Time to go to bed!

You wake up the next morning and all of your riches have been stolen! You call the police and they call you a fool (ふ)! Pardon me?! "You basically put an advertisement on your roof telling everyone you're rich. Of course you got robbed, you fool."
You poor sad, no longer rich fool.
