Wana Stroke?

There were three old ladies sitting on a park bench talking amongst themselves when a flasher came by.

The flasher stood right in front of them and opened his trench coat.

The first old lady had a stroke, so the flasher moved to the second old lady and a after a leer she had a stroke!"

He then turned to the third old lady who would have had a stroke, but she couldnt reach that far.
