The old Hole-in-the-Body Gag. This time from “Ventriloquist Cat” (released 1950), written by Rich Hogan and directed by Tex Avery.
Spike sees the huge stick of dynamite.
The effects animator goes to work. Here are the first two explosion drawings.
And here’s the hole. I’ve always liked the little gag at the end where the duck serenely flies through the hole.
Grant Simmons, Mike Lah and Walt Clinton get the animation credits on this one.
