Strange, but not bad per se
Landlords come in all shapes and sizes. This particular set of landlords were former carnies, so you can imagine what sort of weird things the tenants saw. However, judging by the story, nothing went bad in the home. In fact, things were as normal as could be, given the circumstances.

The only oddities they’d come across were seeing naked people in the swimming pool and the landlady’s friends from her carnie days. Some of those friends were sword swallowers. They probably performed one of their acts in front of the OP. That’s how he found out what they did. Maybe.
