The clown building is over in that part of town. We keep the clown part as separate as we can from the rest of the normal people. In fact, the entire clown education department and their clown clubs have to stay in their part, they can't come in ours.
You see, that part of town is full of booze (ぶ). Clowns need a lot of booze to keep their charade going, so we just let them have it. But they aren't allowed in our part anymore, because they all stink of nasty clown booze.
