We were starting an electronic registration system at school, a lot of information was being held electronically, some years ago. I told my registration group that, because of this, the office would be able to print address labels for their parents' communications but they, the pupils, needed to write out their parents' names and addresses 21 times, a 7 x 3 layout, on a sheet of A4 that would then be scanned and used to print peel off labels. Quite a few of them started again because their writing wasn't their best! At the end, they were told to put them into File B 1N. They weren't happy but impressed with the April Fool!
