A guy goes to his doctor complaining about intestinal problems.
The doctor asks "How's your bowel movements?"
Guy says "No problem, I have a morning constitutional every, single day at 8:15AM"
Doctor then takes some X-rays and says "There's your problem, you've got three tapeworms in you. We are going to have to operate"

The first tapeworm says "Did you hear that? I'm going to hide behind the heart!"
The second tapeworm says "Well, I'm going to hide behind the liver!"

The third tapeworm says "Forget that, I'm taking the 8:15 out of here in the morning!"
