Dr. Giggles

This town has a doctor and his name is Rendell
Stay away from his house 'cause he's the doctor from Hell.
He killed all his patients, every last one,
And cut out their hearts, purely for fun.
So if you're from Moorehigh and you get sick
Fall on your knees and pray you die quick.

—Jump rope rhyme by the children of Moorehigh

Dr. Giggles is a Slasher Movie from the year 1992. It was directed by Manny Coto and starred Larry Drake, Holly Marie Combs and Cliff De Young. It is notable for both its horror and its comedy.

35 years ago, a man by the name of Dr. Rendell in the town of Moorehigh was found to have been ripping out the hearts of his patients with the help of his son Evan Jr. in an attempt to bring back his dead wife. Dr. Rendell was stoned to death by the townspeople, but his son disappeared. 35 years later, the now full-grown Evan Jr. murders two doctors and escapes the asylum that he was in and returns to Moorehigh as the insane Dr. Giggles, intent on revenge for his father.
