Dear Examinator,

I loved your golden oldie - and I've got one
as well:

Sister Mary Virgilius was giving her usual
pep-talk to the Wednesday morning assembly
at her all girls' high school -
gathered in the school auditorium.

After all the usual warning instructions to
the girls regarding chastity and morals -
Sister Virgilius finished the oration with the words:

"And remember girls, one hours' pleasure will
have you damned to hell for eternity."

A little voice spoke up from the back
of the auditorium:

"Sister Virgilius, how do you make it last an hour?"

:-)
