That is a really stupid title for a post.
I was watching Bikdiponabus's Majora's Mask LP. He came across a witch who flew out of her chimney on a broom stick. Bikdip's co-commentator wondered why she didn't just use a door.
And my idea was that I need a building where the inhabitants fly so the only entrance/exit is on the top.
Then I also had an idea for a gigantic beehive. It is a separate idea.
