He's Dr. Cesspool! One day at the hospital... Dr. Cesspool: I've done it again, nurse! Another successful operation! Nurse: Did you remove the patient's appendix, Doctor? Dr. Cesspool: I did better than that! I removed both of them! Nurse: Both of them?? Doctor, people only have one appendix! Dr. Cesspool: Really? Then what is this? *Will Doctor Cesspool please return to surgery immediately?
