Faux Symbolism: Sometimes strips seem to be written specifically to critique modern politics, such as the strips dealing with Arthur's interactions with Rome or the Saracens. Usually this prompts Gadzikowski to step in and say that it's from the source material and the appropriateness to modern times is totally incidental.
Hilarious in Hindsight: In a very early strip, the first sign of Lancelot's homophobia comes when Arthur mentions Bedivere and Kay are "very close" and then has to tell him it's not what he thinks (because Bedivere's female). Two retcons later, it is.
MST3K Mantra: Pretty much the only way to make Arthurian legend work when transplanted into the American Wild West.
Recycled Script: Some gags from King Arthur In Time And Space get adapted when the strip reaches the appropriate point. Arthur's webcomic occasionally reuses plots from Gadizowski's old Life Embellished comic.
