Jon was a science fair judge at a local elementary school this past Wednesday. He awarded the "most creative" prize to a kindergartener who tested whether Christmas exists (Jon said her parents must have been watching a lot of FOX news, with its raging debate over the p.c.'ness of "merry christmas" greetings).
For her experiment, she would greet people with, "Merry Christmas!" then ask them whether they thought Santa Claus existed. Of course, all the adults said "Yes," (what else would you say to a kindergartener?) So, 100% of adults said Santa Claus existed, and 70% of children agreed, therefore: Christmas exists!
Another experiment: a girl tested whether her dog was colorblind. She would show him colored pieces of paper, saying the name of the color several times "PINK! .. PINK! ... PINK!" etc. Then she laid out the pieces of paper on the ground, put doggie treats on each of them, then said the name of a color. She observed that the dog ate all the treats in "random order," therefore he is not colorblind.
I'll leave you to figure that out.
