Hah I should have known it was Grant Morrison. I remember reading one anecdote at the beginning of one of his comics from one of his publishers that was something like “every time I get a call from Grant Morrison it goes something like “the green lantern scottish gibberish that brings Joan of Arc more Scottish gibberish then float through the river Styx roight?””

Which I thought was hilarious.
