Chinese Laundry
A woman sends her clothing out to the Chinese laundry.
When it comes back there are still stains in her panties. The next week
she encloses a note to the Chinaman that says, "Use more soap on
panties."
This goes on for several weeks, the woman sending the same note to the
laundry.
Finally fed up, the Chinaman responded with his own note that said, "Use
more paper on ass."
