The Daffy Doc is a 1938 Looney Tunes cartoon, directed by Bob Clampett and starring Porky Pig and Daffy Duck.
- And Starring: The opening has "Featuring Porky" billed under the main title.
- Body Inflation Gag: After getting his head stuck in the Iron Lung, Daffy's head starts expanding and contracting like a balloon. He tries to hold it still, but that just causes another part of his body to expand and contract. In the end of the cartoon, both Daffy and Porky get stuck in the Iron Lung again, causing their body parts to expand and contract again.
- Hypocritical Humor: Dr. Quack thinks Daffy is crazy, but he turns out to be looney as well when his patient is revealed to be a football.
- Mad Doctor: Daffy Duck, natch. He's more than eager to saw open Porky's stomach.
- Not So Different: Both Dr. Quack and his assistant Daffynote are crazy, but in different ways.
- Pun-Based Title: On Daffy's own name, of course.
- Punny Name: Dr. Quack, Daffy's boss.
- Screwy Squirrel: Daffy Duck heckles Porky Pig and causes no shortage of mischief throughout the cartoon.
- Serious Business: Quack treats sewing up a football with all the concentration and urgency of performing surgery on a live patient.
- Shout-Out: At one point, Daffy holds up a sign saying "Silence is foo.", a reference to Bil Holman's Smokey Stover, one of Bob Clampett's favorite comics.
- Talking to Themself: Daffy does this very literally by bonking himself on the head so he can talk to his conscience about what to do with Porky.
- Visual Pun:
- Daffy is revealing to be hiding a huge pile of pins under his hat. He's a pinhead.
- Daffy brags that he has a "sheepskin" (slang for diploma) and a license, then pulls out a sheep's skin and a license plate.
