~ The French Taunter's most famous line.

The French Taunter is the main antagonist of the movie Monty Python and the Holy Grail, portrayed by British comedian and Python member John Cleese. He is not exactly a villain in the traditional sense of the word but rather a very obnoxious obstacle that King Arthur and his men face when trying to get the Holy Grail - he was part of a group of French soldiers who have mysteriously arrived in England and taken command of a castle which they refuse to share: he is the loudest and most insulting of them all and despite King Arthur trying to reason with him simply treats them all with contempt and denies them entry.

When King Arthur and his men finally lose patience with the troublesome trickster he and his men assault King Arthur and his group in a way that could only of come from the surreal minds of Monty Python - by catapulting livestock at them (including a cow) - this forced King Arthur and his men to retreat, so in some ways the French Taunter is a villain who succeeded...albeit in a very strange manner and for reasons that can probably never be fully explained.

In Game of Thrones, the French Taunter's taunts can be heard in dialogue, albeit translated into Low Valyrian.
