Three old Ladies named Gertrude, Maude, and Tilly were sitting on a park
bench having a quiet conversation when a flasher approached from across
the park. The flasher came up to the ladies, stood right in front of them
and opened his trench coat.

Gertrude immediately had a stroke.

Then Maude also had a stroke.

But Tilly, being older and more feeble, couldn't reach that far.
