I get a newsletter from Philip Humbert and in one awhile back he asks some good questions:
Why doesn’t Tarzan have a beard?
Why does Superman stop bullets with his chest but ducks when revolvers are thrown at him?
What is the speed of darkness?
Can you cry underwater?
Why does a round pizza come in a square box?
Why do doctors leave the room while you change?
Actually, we tried to sell pizzas in a round box for a while but the feedback was negative – too unconvinient to get the pizza out of the box.
