From Jason Kottke:
Me: Yeah, it's like the plural of attorney general is attorneys general.
J: Attorneys general? I thought there was only one attorney general.
Me: Well, one for each state, and if they all go to a meeting or something...
M: Like, "all the attorneys general get together for the annual attorney general-a-thon."
Me: Shouldn't that be attorney-a-thon general?
