One day a man went to see a doctor. He yelled, "Doctor, doctor, you've got to
help me."

Then the doctore asks, "What's wrong?"

"Well," the man said, "yesterday I ate a sandwich. When 'it' came out, it
looked like a sandwich. This morning I ate a piece of pizza. When 'it' came
out, it looked exactly like a piece of pizza. What should I do, doctor?"

"It's not so hard, is it?" the doctor replied. "You know what you have to do?
Try to eat some shit!"
