Soap
From Tardis Wiki, the free Doctor Who reference
Soap was sometimes kept in dispensers.
History
Soap did not exist in 2700 BC Mesopotamia; instead, skin was scraped with a dull knife, then rubbed with perfumed oil. (PROSE: Timewyrm: Genesys)
In the 1890s, Euxesis was advertised as a shaving cream without the need for use of soap, water or a brush. (TV: Deep Breath)
In 200,100, after Crosbie was evicted from Big Brother, she apologised to Lynda Moss for stealing her soap. (TV: Bad Wolf)
