A toilet seat is the seat and lid of a toilet. Automatic toilet seats in Japanese toilets may include a large number of features, including a bidet, a blow drier, and a heated seat. They come in a wide variety of shapes, from the normal porcelain ovate seat to the opened-front seat often seen in public restrooms. They can be made of porcelain, plastic, steel, ivory or wood. Some metal toilets, such as those in many jails and prisons, have built-in toilet seats.
The toilet seat is a comic staple for sight gags relating to toilet humor. The most common is someone staggering out of a bathroom after an explosion with a toilet seat around his neck. In the television show Dead Like Me, George Lass, the main character, is killed when a zero-G toilet seat from space station Mir re-enters the atmosphere.
In 2004 Senator Chuck Grassley (R Iowa) said: "I exposed the spending scandal in the '80s when federal bureaucrats saw no problem in spending $600 for a toilet seat . . .". Some now claim that neither that nor his also famous revelation of the Pentagon spending $400 for a hammer actually ever happened. Others say the prices paid were fair and justifiable.
