On hearing that her elderly grandfather had just passed away, Jenny went straight round to visit her grandmother.

When she asked how her grandpa had died, her granny explained, "He had a heart attack during sex on Sunday morning." Horrified, Jenny suggested that having sex at the age of 94 was surely asking for trouble.

"Oh no," her granny replied, "we had sex every Sunday morning, in time with the church bells.

She paused, and wiped away a tear.

"If it wasn't for that dang ringy-ding-ding ice cream truck going past just as the church bells were ringing, he'd still be alive."
