Sir Francis

Panel 1- Stan: " Sir Francis, you planted plants with thorns ( to discourage jaywalkers ) but it has no effect.."
Panel 2- Sir Francis: " It's because jaywalkers are thick-faced so they are not ashamed to cross the street even though it's not allowed.."
Panel 3- Stan: " They are also thick skinned so they don't feel pain from the thorns of the plants.."
