The Doctor tells his patient that he has H-E-G-S

"What's that?", the patient asks.

"It's a combination of Herpes, Encephalitis, Gonorrhea and Syphyllis."

The patient wants to know if there's a cure, to which the Doctor responds,

"We have to keep you in a hospital room and feed you nothing but pancackes."

"Why only pancackes?", asks the patient.

The Doctor answers, "They're the only thing that will fit under the door."
