TiVo Knows our Basement Flooded

We've all heard the story - TiVo users who recorded Will & Grace found TiVo interpreted that as Indicative of Personal Preferences, as reported in the Wall Street Journal Article "If Tivo Thinks you are Gay"

I get how Tivo starts with an alternative lifestyle comedy and arrives at "You play for the other team". Really, I do. But explain to me why it is that TiVo recorded "Ask This Old House - StormWater Drainage" a mere 6 days after our small basement disaster? We have never recorded This Old House. We didn't select this episode. TiVo Chose it for us. TiVo has not chosen to record This Old House before or since this episode. Creepy.
