That shower is filthy.
We had family friends that had a rec-room in the basement with walls made up of shelves and lined with 2000 or so beer cans, mostly all different. There were boxes of cans they'd run out of room for. As you might imagine, there was a "tour" of the collection conducted for flabbergasted newcomers. Years later, when selling the house, they were fortunate to find a buyer that wanted the collection and bought the house as-is.
Perhaps this seller got lucky too and a die-hard Budfan batchelor snapped it up. (And won't mind the shower.)
