On the old Mickey Mouse Club television program. Tuesday was "Anything Can Happen Day.
What can happen today?
I might get my syllabi for next semester finished.
I might do laundry, filing, exercise.
I might let my imagination take me to a dance class, to western town, World War I battlefield(I am reading a Harry Turdledove novel), or I might take a trip on a space ship like Serenity or the Enterprise if I decide to watch television.
Anything can happen.
