I think it's ridiculous how some fan wikis list April's middle name as "Harriet" as an official part of continuity, sometimes across every continuity of the franchise. All because it was mentioned as a throw-away gag in "Leatherhead, Terror of the Swamp." I can't remember if Irma's last name was ever mentioned in any episode, but I have accepted the Langinstein designation in my own mind.
