I'm sure I did, but nothing comes clearly to mind. However, there might have been a book report or two that was "lifted" from the back cover- or strongly edited from such. Like the teacher couldn't figure it out!
OH! I just remembered... at Girl Scout camp, there was a camper who'd sign off on individual badge requirements. I remember that counselor 'assigned' her to do this, as there were so many of us and only one counselor, but I am 99% sure that more than the completed requirements were signed.
