Every episode features a different twist on Porky's "That All Folks!" line, usually having to do with the events of that particular episode.

Following the closing credits, Porky Pig opens up the Warner Bros. "WB Shield" logo like a door and delivers his famous "That's All Folks!" line.

In a reference to the 3-D Bugs Bunny cartoon "Lumber Jack-Rabbit" (1954), the opening WB shield logo that normally zooms forward in the classic cartoons overshoots its mark and crashes into the screen before moving back into its usual position at the start of the series opening credits.
