What did you do to make your neighbors think you are crazy?

When I first saw a bathtub used as a raised bed, I thought it was a brilliant idea. I admit, my property is not visible to neighbors.

I used an old toilet for one year.  That first winter the water froze in the trap and broke it.  
It definately was a sight to see flowers blooming out of the bowl !  (I did take a few pictures of it, but can't find them, If I do I will post them)
