I did some rudimentary string parsing on submit, and if the question started with a word like "Where", "How", "Why", "Who" and a few other words that signified the question couldn't be answered with Yes or No, it would show an angry photo of his face with the caption "Your question has angered chuck!" - I think I also gave it a 1% chance to randomly roll that result regardless.
My dad absolutely loved that little project, and reminded me of how funny he found it even this year shortly before we lost him, almost 2 decades after I'd made it.
Sorry this wasn't incredibly related to your submission, but I wanted to share a happy memory you just brought back to me with it.
