"WHERE is my SUNDAY paper?!" The irate customer calling the newspaper office, loudly demanded to know where her Sunday edition was.
"Madam", said the newspaper employee, "today is Saturday. The Sunday paper is not delivered until tomorrow, on SUNDAY".
There was quite a long pause on the other end of the phone, followed by a ray of recognition as she was heard to mutter ..."Well, shit, that explains why no one was at church either".
