Funny Toilet

The standalone toilet has been variously known as backhouse, house of ease, house of office, little house, or outhouse.
The "house of office" was a common name for a toilet in seventeenth century England, used by, among others, Samuel Pepys on numerous occasions: October 23, 1660: ...going down into my cellar..., I put my foot into a great heap of turds, by which I find Mr Turner's house of office is full and comes into my cellar.
• Latrine
Latrine is a term common in the military, specifically for the Army and Air Force for any point of entry facility where human waste is disposed of, which a civilian might call a bathroom or toilet, regardless of how modern or primitive it is. Traditionally the Royal Navy along with the United States Navy and Marine Corps use the nautical term "Head" to describe the same type of facility, regardless of whether it is located on a ship or on the land.
