my nephews and niece came up with a few like that growing up...
niece went to a fairly progressive school at the time, they all used laptops for classes
niece - Home for the day, school was let out early!
hal - Why?
niece - the school server went down
hal - So that allows everyone to leave school?
niece - Well duh yes Uncle Hal, how are we supposed to learn!
hal - Umm, do they have books?
niece - lol! you so funny Uncle Hal, we need pc's to do actual work!
hal -
amazing that teachers cant teach without it all done up ahead of time
