June 2nd, 2023: Over on my Patreon - where you can both support the comic and read TOMORROW'S COMIC TODAY - Phillip pointed out that the Cracked De-Textbook is basically what T-Rex is describing here!

One year ago today: YES it's the hp-41cx and YES i love it and YES it was passed down to me by my father
