It was a blazingly hot summer afternoon as I walked the dog. We walked down Broadway, where an electronic sign announced that both interstate lottery jackpots were around a quarter-billion dollars. I felt like daydreaming on my dog walk, so I stopped at the newsstand with the lottery terminal.

“One Mega Millions and one Powerball, please,” I said to the older man working the newsstand.

“One of each?” he said.

“Sure,” I replied, “maybe they’ll both come in.”

He paused a beat while the tickets printed. “One is enough,” he said.
