Hard dried up rubber circular ornament on the corner of the bath (that large porceline oval near the shower used to temporarily store laundry) and oft picked up by small children who ask... "Mummy? What is this hard dried up rubber circular ornament used for?) those small poor babes who dont remember when it wasn't illegal to fill a bath to the top and soak and play with yellow rubber decoy baby birdlife in a sea of bubbly wonder. Hard dried up circular ornament on the corner of the bath that still cant be used because the laws and water restrictions per household came in during the 100 year drought even though most of the state and indeed the eastern seaboard in now declared a disaster zone from floods for the past four years. Hard dried up rubber circular ornament on the corner of the bath that would most probably shatter if after all these years came into contact with water.
Edit: Hmmmmmmmmmmmm...... Hard dried up rubber circular ornament on the corner of the bath that if inserted into circular drain in bathtub and covered in generous amounts of H2O whilst householder is soaking in bliss in said H2O MAY lead to sudden and interesting meetings with tall strong gorgeous Water Police bursting through the bathroom door to read me my rights and drag said towel wrapped soggy householder off to be interrogated.

Most probably just get a letter of enquiry about overuse of water and a water bill in the mail from the council......
