* "No negotiations in the cemetery" - really! like one of the attendants approaches you asking for a mitzvah in the amount of X gryvna, you are not suppose to tell him that you can only do X/4.
* "Do not sleep in the cemetery" - you are taking up space that could be used by the other 20,000 forgivness-seekers and mitzvah-providers.

and the last one is my favorite...
* "Women should REFRAIN from raising their voices, and pray quietly and modestly" - just no comment :)
