On hearing that her elderly grandfather had just passed away, Sally went straight round to visit her Grandmother.
When she asked how her grandpa had died, her gran explained, "He had a heart attack during sex on Sunday morning."
Horrified, Sally suggested that shagging at the age of 94 was surely asking for trouble.
"Oh no," her grandma replied, "we had sex every Sunday morning, in time with the church bells -- in with the dings and out with the dongs."
She paused, and wiped away a tear.
"If it wasn't for that damn ice cream van going past, he'd still be alive."
