seeing as there appears to be "reading material" next to said Toilet- I'm going with FIL came to visit- and the toilet is where he spends his time- so out it goes.
I think I would have to grab a newspaper and sit on it with my pants around my ankles for a while just to allow passerbys to have a little chuckle.
Seriously though (or at least as close to serious as this can get) it is probably a remodel. My brother is a contractor and if the toilet was functional he would put it out on the curb early so if anyone wanted it they could take it before the garbage men did.
