Say the following:
"My father shovels ashes at the shipyard."
Now please stick out your tongue and pinch it (gently) between your forefinger and thumb.
Without letting go of your tongue, say "my father shovels ashes at the shipyard" once more.
Congratulations, you're seven again.
To my great surprise, a Google search on the phrase quoted above appears nowhere on the intrawebs.
But now it does. My job is done for this evening.
Sister Mary Noel, late Principal at the Saint Martin de Porres Elementary School in Red Oaks Mill, New York would be oh so proud right now to know that I've shared this with all of you.
