I own and manage a lot of residential rental property. If you can dream it up, ive seen it in our apartments at one point or another. I could have a reality show and never have to fabricate anything. This particular tenant has lived with us for quite some time. He's a really nice guy and is a workout nut. Dude runs everywhere. Super fit. We had to evict him for lack of payment and when we got possession of his property, i had no idea i would find this in his apartment. lol, i was impressed but also baffled.
