Little Noah came into the house with a new harmonica.

 "Grandpa, do you mind if I play this in here?"

"Of course not, Noah. I love music. In fact, when your  grandma and I were young, music saved my life."

"What happened?"

"Well, it was during the famous Johnstown flood. The dam broke and when the water hit our house it  knocked it right off the foundation. Grandma got on the  dining room table and floated out safely."

"How about you?"

"Me? I accompanied her on the piano!"
