The Annual Physical

After his annual physical, the old perfesser was waiting in the doctor's office for the results.

"Well," said the doctor, "I have good news and bad news for you."

"The way I feel, please give me the good news first," replied the old perfesser.

"The good news," announced the doctor, "is that your penis has grown an additional four inches since your last exam."

"Great!" the old perfesser shouted. "What's the bad news?"

"It's malignant," replied the doctor.
