Porky in Wackyland

At one point in the pan of the various denizens of Wackyland, a character with large glasses comes out of a pot and says, "Hello, Bobo." This refers to animator Robert Cannon, whose nickname was Bobo and who did wear big glasses. On the pot are the words "Treg's a Foo", refering to sound effects man Treg Brown. (Foo, incidentally, is a nonsense word from the Smokey Stover comic strip, a big influence on this cartoon in terms of humor and visual style.)

In the Wackyland sign, the words "It Can Happen Here!!" are underlined (with "Can" being double underlined) on close-up, but are not underlined in long shots.

A paper boy walks onto the title card and thrusts the newspaper with Porky in the front page into the camera, covering the entire screen. After enough time for the audience to read the headline, the camera dissolves to Porky in his plane.

The colorized version is actually censored. The scene where the prisoner behind bars he holds up ends with his complaining. In the original, he's beaten by a jailer. Many characters are cut out, and the ending is completely different.
