Kids and a Typewriter...
The kids discovered an old typewriter in the attic. Though it was old, it was still well preserved. Of course, dad had to explain... He got a sheet of paper, put it in the machine, and started typing... The kids were amazed, and started firing questions like: Where do you plug it in? Dad says "you don;t have to plug it in". Where are the batteries? Dad replies "no batteries needed". What software does it use? Dad (smiling) says "no software required". Kids: "WOW Dad! Why didn't they invent this LONG AGO?!"
