three nuns are sitting on a park bench a man walks up to them and exposes himself two of them have a stroke , but the other one could n't reach .
What did you intend with this joke about religious adherents?
To point out that celibate people are the most sexually frustrated.
Nuns are women who have chosen to devote themselves entirely to their religion, and they have freely decided to give up on sex.  It is unfair to suggest that they are sexually repressed, because this implies that they did not make their own choices in life.
