My wife wouldn't stop asking me to help her with FB. As a joke I told her if she didn't quit, I'd delete it (Tech stuff goes over her head like a 747). Well, she kept on so I opened up the Dev tools. I started by adding just some non sense to one of the divs. She saw it pop up on screen and was like "Wait...you can really do that?" then I highlighted the body tag and hit backspace. The whole thing disappeared, it was great. She legit freaked out for a minute and begged me to fix it. I popped up the console and started typing random things. Created an array with some mumbo-jumbo, a couple of quick, meaningless functions and snuck hitting Ctrl+R in there, refreshing the page. She was so happy that Facebook worked again, that she stopped asking me how to do whatever it was
