When my wife quit work to take care of our new baby daughter, countless hours of peek-a-boo and other games slowly took their toll.

One evening she smacked her bare toes on the corner of a dresser and, grabbing her foot, sank to the floor. I rushed to her side and asked where it hurt.

She looked at me through tear-filled eyes and managed to moan, "It's the piggy that ate roast beef."
