The Toilet-sink, A Must-Have for the Modern Home

I was browsing through my local used building material store when I came across this, um, contraption.  At first I thought, water-saving toilet?  Something for a boat?  When I walked around to the back I saw that the sink drained directly in to the toilet bowl with no toilet tank so there wouldn't be much water savings.

When I got back to my computer I looked up "toilet-sink" and found an image that looked just like it.  I guess I haven't been watching those cop shows carefully enough because what I stumbled on was a prison cell toilet.  Now that would be an interesting conversation starter.  In fact, I could add it to my front yard décor for my mobile home.  I'm thinking toilet-sink fountain right next to the bathtub planter.  All it would need was an outdoor shower to complete the theme.
