The Impatient Patient

While traipsing through the Ookaboochie Swamps, Daffy Duck seeks to deliver a telegram to "Chloe". Unable to find the telegram's recipient, and suffering from a severe case of hiccups, he stumbles upon the home of "Dr. Jerkyl" and hopes that the physician can cure his condition. Daffy's hiccups are so severe that they cause him to damage or destroy everything around him.

Dr. Jerkyl captures Daffy and restrains him to a doctor's chair. Hoping to scare Daffy in order to cure his hiccups, Dr. Jerkyl creates and drinks a potion that turns him into Chloe, a grotesque ogre. Daffy, realizing he has reached his destination, then reads Chloe the telegram: the lyrics to "Happy Birthday To You" (albeit spoken and not sung), sent to him by Mr. Frank N. Stein.

Chloe, who is enamored with Daffy (who, in turn, is now cured of his hiccups), chases the duck around the laboratory until the radio is accidentally switched on, prompting him to dance. Once the music ends, the chase resumes. Daffy scrambles to the lab table and mixes a potion, which turns Chloe into an infant. As each brandishes a hammer insisting each one doesn't know the other that well (doing imitations of Red Skelton's "Mean Widdle Kid" character), the action moves offscreen, a large thud is heard, and the bird from the doctor's cuckoo clock displays a large sign reading “He Dood It!” The baby Dr. Jerkyl then screams "Ooo, you broke my little head! Ooh you broke my little spine! Oh!"

This cartoon was colorized in 1968 (just after Seven Arts Productions, successor to Guild Films, to whom the TV distribution rights to the black-and-white cartoon library had been sold some time before, acquired Warner Bros.) by having every other frame traced over onto a cel. Each redrawn cel was painted in color and then photographed over a colored reproduction of each original background. The animation quality dropped considerably from the original version with this method.

The cartoon was colorized again in 1992, this time with a computer adding color to a new print of the original black and white cartoon. This preserved the quality of the original animation (the end result also resembled the actual color cartoons released around the same time).
