I used to believe that there was one santa for every country, just to make their job easier, then when I stopped believing in the santas, I thought elves did all the work.
When I was in first grade I'd trick my parents into making up notes that I had a horrible disease that kept me from going out to recess. They thought I was only playing with the notes, and of course I couldn't read well, so I didn't know what the heck was written on those notes. I'd actually take them to school and tell the teacher about it, and gave him the notes. Well, the notes actually said things like, "This is for play only, note note notey." and so on. After a while the teacher called my parents about it and I don't think I've had the courage to make up a note since then.
