Upon hearing that her elderly grandfather had passed away, Katie went straight to her grandparent's house to visit her 95 year old grandmother and comfort her.
When she asked how her grandfather had died, her grandmother replied , "He had a heart attack while we were making love on Sunday morning." Horrified, Katie told her grandmother that 2 people nearly 100 years old having sex would surely be asking for trouble.
"Oh no, my dear," replied granny. "Many years ago, realising our advanced age, we figured out the best time to do it was when the church bells would start to ring. Nice and slow and even. Nothing too strenuous, simply in on the Ding and out on the Dong."
She paused to wipe away a tear, and continued, "He'd still be alive if the ice cream van hadn't come along."
