I remember noticing a few things in Game of Thrones that suggested GRRM was having a little fun. Re-reading again a couple have already struck out as potential jokes outside of the text.
1. Blackadder
It appears here that GRRM is plainly tipping his hat at the BBC period comedy, and shoves it into the middle of a list so it's easily overlooked.
2. Marillion
1. Blackadder
Blackadder? Is this really a major heraldic symbol? Even if we accept the argument that it might be, surely it would be spelled "black adder"?The shields displayed outside each tent heralded its occupant: the silver eagle of Seagard, Bryce Caron’s field of nightingales, a cluster of grapes for the Redwynes, brindled boar, red ox, burning tree, white ram, triple spiral, purple unicorn, dancing maiden, blackadder, twin towers, horned owl, and last the pure white blazons of the Kingsguard, shining like the dawn.

2. Marillion
Well, perhaps on the radio? Or on TV? After all, Marillion is a very successful British rock group with chart-topping hits such as Kayleigh. It would be a remarkable coincidence if it isn't, though I remain uncertain what GRRM is trying to use this character to say, other than he finds Marillion very annoying.“My name is Marillion,” the singer said , plucking a string on his woodharp. “Doubtless you’ve heard me play somewhere?”
