Waterfoot Auction and the Suction Dildo

I went to Waterfoot auctions on Friday to view the stuff for sale that evening.  All the stuff, without exception is crap.  I often wonder what happens to the stuff that invokes the interest of the staff at the local recycling centre, now I know.

One of the items I saw was a dildo with a suction cup.  This puzzled me slightly.  The only place a suction cup like this works is on a window and I've never witnessed anyone doing dildo stuff on a window, either in a house or car.  Is that why they made a sex comedy movie called 'Confessions of a window cleaner'?
