Tillie - Maude - Gertrude

These three old ladies and their dogs 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 Tillie, being older and more feeble, couldn't reach that far.
