A general rule for the public:

I'd like to talk about an unwritten rule that the public should start to follow a little more closely. If you happen to have been prescribed and use medications administered rectally or vaginally, please just call in the prescription number to the pharmacy. Do not bring in the container. Yes, you are special and you wash your hands, wear latex gloves and pray for forgiveness while doing the deed. I get that, thanks, whatever, just don't bring in the box or bottle. If there is any chance that your hands might travel back to the container after tickling your duodenal sphincter, leave it home, decontaminate it, burn it and throw it away. I hope you get the message.

Oh, and one last thing. I've got a friend in the industry, so he would know... no oral sex before going to the dentist. They'll know.
