A struggling Folksinger went to a doctor and reported on his condition, saying, "Doc, I can't go to the bathroom."

Writing out a prescription, the doctor said, "These pills will do the job."

The Folksinger left but returned a week later. "Doctor, I still haven't gone to the bathroom."

The doctor wrote a second prescription. "These are stronger. The should do the trick."

A week later the Folksinger came back, still with bad news. The doctor looked at him and said,"What do you do for a living?"

"I'm a folksinger."

"Why didn't you tell me before?" With that, the doctor wrote out another prescription....FOR FOOD !!
