This time we're getting into terms of etiquette and the origins of certain expected behaviours, starting with the word etiquette itself, which shares a root with ticket because rules of behaviour were once written on small tabs.

Forks were originally viewed as pretentious tools before becoming symbols of proper dining. In this context protocol refers to the formal rules that govern conduct, and its etymology goes back to the 'first page' of a document, from ancient Greek roots meaning first and glue. The episode also uncovers the origins of terms describing poor behaviour, including crude, vulgar, uncouth and boorish, the last of which is linked to the Dutch, along with expressions such as hoity-toity, toffee-nosed and la-di-da.
