Yesterday afternoon, my five-year-old son, Kaleb, came up and asked if I had a penny.
"Yes, I think I do. Why do you want one?"
"We can go to Pizza Hut and buy a pizza for a penny."
"I think you have to buy a pizza at the regular price first, then we can get the next one for a penny."
"Well, we could call Dedad [grandpa] and have him buy the first one, then we could buy another one for a penny."
