Why is the sky blue? How do the birds fly? Why do idiot drivers always end up in front of me in the morning on my way to work when I am running late? Why do the best movies always have scratches on the DVD just when you hit the good part? Why is 'Times New Roman' the default font of word processing programs? Is there anything smaller than a quark? Where does the work 'lesbian' come from? Do small breasted women have to supplement their breast milk with formula to keep up with the demands of a hungry baby?
