Heckle & Jeckle are otherwise known as the "Talking Magpies". That happens to be the title of our next subject.
"The Talking Magpies" was released in January 1946, and technically is also a Farmer Al Falfa cartoon, as he appears with a prototype for Heckle & Jeckle's occasional foil, Dimwit Dog. The big difference, as you'll see, is that the birds in this story are a married couple looking for a place to call home. By the time Terrytoons came back with another short, the marriage was, well, dissolved, and the team we came to know as Heckle & Jeckle took over.
This has, to my knowledge, not been a regular part of the Heckle & Jeckle syndicated package.
Sid Raymond, the voice of Baby Huey, also did the voices for this cartoon.
