Sexomatic 5000
From SquackleWiki
The Sexomatic 5000 is a machine that projects light against the roof and makes it look like thousands of fat loads of poo are in the sky.
Part of the Sexomatic 5000 is a 200-inch reflecting toilet that allows you to see many family jewels that are millions of dicks away.
