Permanent What?

A man went into a local pharmacy and asked to talk to a male pharmacist.

The woman behind the counter informed him that she was the pharmacist.

She told the man that she and her sister owned the store, so there were no male pharmacists employed there. She then asked if there was something she could help the gentleman with, as she had been a licensed pharmacist for many years.

The man shrugged his shoulders and agreed to share his problem. "Okay," said the man, "but this is a bit embarrassing for me. I have a permanent erection, which causes me lots of problems and severe embarrassment. I was wondering what you could give me for it?"

The pharmacist said "Just a minute, I'll go talk to my sister."

When she returned, she said, "The best we can do is 1/3 ownership in the store and $3,000 a month in living expenses."
