Granddaughter visits Grandma because Granddad had passed away yesterday morning.
"Oh Grandma, I'm so sorry. What happened? "
"Well, we were making love and your Grandfather suffered a fatal heart attack."
"Making love! ? Granddad was 91 and you're 87. That's too old for love making."
"Well, we learned a technique about 30 years back that allowed us to continue making love the rest of our lives. Every Sunday morning we'd make love to the easy rhythm of the church bells ringing. This has worked perfectly for all these years until yesterday when that damned ice cream truck came by."
