Continuity mistake: The book the coyote is reading has "How to Tar and Feather A Road Runner - 10th Printing" on the front cover, but when we see the coyote reading the book in the next shot, the words have disappeared.
Continuity mistake: When the coyote is about to eat a tin can at the start of the cartoon, the bottle of wine in front of him changes position between shots.
Other mistake: Philip De Guard is the cartoon's layout artist, yet when we see his name in the opening credits, it is spelled "Phillip" instead of the usual "Philip."
