I'm actually looking forward to this for about a few months! It's quite related to the series, but not in the publishing, but more in the production: Usually when I change a line or a small action in the script, I inform Kame (The Artist) when the page is still a sketch (Never in Lineart, that is the Event Horizon of the production), and usually we use that stage of the drawing to settle things like minor changes, bubbles, panel and etc... (Or if a part was skipped)... But this time, the Joke consist in telling her something like "I totally changed the script, we have to re-do all the sketches" (Gently of course), then I hand to her a .doc file... with "APRIL FOOL" Written all over it... and to sell the trick more without any suspiscion, I would fill it with white colored "Lorem Ipsum" so that the file size looks convincing, when there is actually nothing! I really would love to see both her reaction before and after seeing the joke (altough, I'm quite hesitating eh eh...)
EDIT: Why I'm pubblicly saying this and not keeping it for myself with the risk she would find out? I 100% She isn't in the forums... But April fools will confirm it or not if that was the case... eh eh...
