In middle school I used Javascript to change Google's button text from "I'm feeling lucky!" to "Andrew is the best!" (javascript:getElementById('').text='blah')
I showed some other students who were so freaked out that I had "hacked Google" that I got the attention of the librarian, who promptly banned me from the library computers for the rest of the year, even after I refreshed the page to show them it wasn't "real". Oof.
