Our parents used to let me exercise my Christmas desires by circling items in the old Sears Roebuck Catalog. I'm sure it was a lesson in disappointment because I rarely got what I circled...probably because I picked out things like a $400 robot. The boys got to wish upon a star with the Fat Brain Toys Catalog. It's good to want things and not get them. Besides, the robot would just break in 2-days! In the video Luke is saying that he is "squaring" things because Jack used circles for his wish list while Luke boxed in his deepest desires.
