Jaquandor once said this about quoting Monty Python at a Renaissance Festival, although this applies just as well to playing D&D:
[...] So it’s with nothing but love and heartfelt concern that I inform you that walking around shouting quotes from Monty Python and the Holy Grail like “I’m bein’ repressed!” and “Ni!” is the Renaissance Festival equivalent of shouting “Freebird!” at a rock concert. Don’t do this, folks. Wandering through a Renaissance Festival with your friends, pretending to debate the airspeed of an unladen swallow, is just shooting fish in a barrel. Don’t do it.
Having said that, just try to get through this part of the movie without thinking about it. I swear the old woman in panel six is just about to say, “There’s some lovely filth over here.”
This really is like shooting fish in a barrel.
