Gordon Keith discovered these water butts. Weird! And they're almost $200. If you're interested, then they do come in three different colors. Here's the site. Here's a description from the site: "The new Butt Butt has been designed for Straight plc by Gerardine & Wayne Hemingway. Keen to develop something new and contemporary the Butt Butt was conceived,
which has the unique feature of being in the shape of a human bottom.The Butt Butt, however, has the advantage of being both a practical rainwater collection container and a fun eye catching feature in any garden.
The Butt Butt is available in three colours and is fitted with a tap. The front of the Butt Butt is flat allowing it to sit neatly against a wall or shed. It can be attached to the downpipe by using its included rain diverter kit.
Capacity: 215 litres"
Here's how a water butt works.
