Boolean Squared: Pulling Pranks on the Teacher

I was riding in a car with a friend the other day. She uses her TomTom GPS to tell her where to drive and I kept getting startled by the voice (I have never used one before). I thought it might be funny to have the kids pull a prank on Mr. Teach by installing the voice of Urth into Mr. Teach’s GPS unit and the best person to turn to for help? Why, Jenni Peg and her mighty brain, of course.

Peace (in the prank),
Kevin
