Ella S. Fish goes to doctor. Doctor says, "Hello, Madame Salmon. What brings you in today?"
Ella Fish replies, "Are you still making that dreadful pun with my name. Anyway, the answer is EVERYTHING. I hurt my back at work, I have a cold, my eyesight is going, and I have high blood pressure."
The doctor raises his eyebrows, jots down some notes on his clipboard, and says, "Okay, Mrs Salmon, what's your lifestyle like? Do you eat healthy, get enough sleep, all that?"
"Oh, yes," replies Ella. "I eat organic, sleep at least 7 hours a night, and I never drink or smoke."
At that, the doctor smiles and slaps his knee. "Well that's your problem!" he exclaims. "Let me write you a prescription for some Marlboros."
Ella is dumbfounded. "Doctor, why?"
The doctor finishes writing the prescription, rips it off his pad, and hands it over.. "You need to start smoking," he says, "because smoking cures salmon, Ella."
