I was going around removing more of the one million electric outlet covers that the previous owners had in this house, and it made me think about some of the quirks other houses I've lived in have had. One house was owned by a telephone company employee, and they apparantly got a discount on installations, because there were phone jacks everywhere. Even though it was a tiny two bedroom, one bath house, you could have had a phone in the bathroom, the garage, the backyard.... There was also a short pole hung on an eye hook inside of the bookcase of another house. No one could figure what that thing was for, but it obviously was important because they had gone to great lengths to make sure it was handy when they needed it.

What's a remnant of previous owners in your house, or something that people would scratch their heads over if you sold your house today?
