A water Bed in a German furniture store. Note that the sign says NOT to get on the bed, but oh well..the best way to motivate people to do something is to put up a sign saying "Don't".
Turn on speakers and watch people trying out the water bed.
It's in German, but that only makes it funnier.
Watch for the last two ladies !http://www.youtube.com/embed/9wm-Ge8LL7o?re
