-What do you mean?! - You snore! - Oh I don't- anyway, you have bad breath! - Because you never brush my teeth! - Oh, stop quickly, let's have a cup of tea! - the three- headed giant's heads arguing
The Three-Headed Giant was a character in the film Monty Python and the Holy Grail. It lived in a northern forest and it's three heads were always arguing about something. Sir Robin encountered this giant while searching for the Holy Grail. It's left head was portrayed by Terry Jones, it's middle head by Graham Chapman, and it's right head by Michael Palin.
When Sir Robin, his minstrel, and his other men met the giant, the three heads frighteningly asked Robin his name. First, the cowardly knight tried to just get away by saying things like "I just came by..." and so, but finally told the giant that he was a knight of the Round Table. One of the giant's heads then wanted to kill Robin, another didn't, and eventually they were all arguing as usual. As the angry heads argued, Robin quickly ran away, frightened, and when the three heads finally stopped arguing, he was gone.
