Upon hearing that his elderly grandfather had just passed away, Dave went to visit his 95 year-old grandmother and comfort her.

When he asked how his grandfather died, his grandmother replied, "He had a heart attack while we were making love on Sunday morning."

Horrified, Dave told his grandmother that 2 people nearly 100 years old having sex was surely be asking for trouble.

"Oh no, dear," replied granny, "many years ago, realizing our advanced age, we figured out the best time to do it was when the church bells would start to ring. It was just the right rhythm. Nice and slow and even. Nothing too strenuous, simply in on the Ding and out on the Dong."

She then paused to wipe a tear, and continued, "He'd still be alive if the ice cream truck hadn't come along."
