My daughter loved the movie "The Wizard of Oz" and wanted a pair of ruby slippers just like Dorothy. My wife found a pair that were perfect, except they were very slippery on the stairs.

I told my daughter not to wear them when she was using the stairs. While sitting in my living room I heard the clomp, clomp, clomp of what I knew to be ruby slippers. I yelled up at my daughter saying, "I thought I told you not to wear those shoes on the stairs?"

She replied, "Daddy, I am just carrying my shoes downstairs with my feet."
