What's the dumbest, trivial, shoddily-written project you've made that somehow impressed a non-programmer?
I wrote a script that grabs an Overwatch screenshot, tries to recognize whatever hero portraits are present on the tab screen, then copies some text making hero suggestions into your clipboard. I'm 90% certain that the one person in the hiring process that sounded impressed when I mentioned it didn't actually look at it, because I got hired to try automating website tests with Selenium.

(Note: I've long since taken this script down as it's in kind of a grey area with Blizzard's TOS)
