Stroke

Three old ladies named Gertrude, Maude and Tilley 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 feebler, couldn't reach that far.
