I received several versions of this one. Jaybee, my friend from out west, sent this version...

Three old ladies named Gertrude, Maude and Anita were sitting on a park bench having a quiet conversation when a flasher approached from across the park.

The man came up to the ladies, stood right in front of them, opened his trench coat and exposed himself.

Gertrude and Maude both had a stroke.

But Anita, being older and feebler, bless her heart, and couldn't reach that far.
