I forged my dads signature from 4th to 8th grade so he would never find my grades when teachers asked our parents to sigh our progress report.
When I read those "choose your own ending" Goosebump book's as a kid I'd mark the page where you got to choose alternative ending's and stuff, and if I happened to choose a page where the character dies or something, I'd just flick back to the choose page again and go to the page I should have chosen first.
