In A Dance with Dragons, when the sellswords of the
talk between themselves, one says about Daenerys' Unsullied that they are
the kind that don't break and run when you fart in their general direction.
It seems to me a reference to Monty Python's Holy Grail when the insulting Frenchman says to King Arthur and Ser Galahad:
I fart in your general direction
So, is it a reference to the Holy Grail, and are there any other references in ASoIaF to Monty Python's work?
