Hot on his Own Trail
Exactly What It Says on the Tin, when a character gets covered with dirt or is walking through the snow, he will look down and see his own footprints. However, because this character is either a Cloudcuckoolander or The Ditz, he will think that his footprints belong to someone else and start following the footprints. It is then that the character is back where he started that he realizes that it was actually his own footprints that he had been following. A subtrope of Going in Circles.

Of course, it's their own tracks, as they have been driving in circles for hours.
- In another comic "Explorers on the Moon", the bumbling detectives Thomson and Thompson walk around the moon's surface and soon, to their surpise (since this expedition marks the first time men set foot on the moon) find footprints and promptly radio the rest of the crew.

- A more high-tech version of this occurs in Now You See Me, where the main character is using an electronic device to tail The Four Horsemen after one of their shows, only for the device to get tagged onto him by one of the persecutee, so the main character would begin tracking him instead. It takes until he plows into and out of a random bathroom before he realizes it.

- In the I Love Lucy episode "Desert Island", the Ricardos and Mertzes tow their gasless boat to a seemingly deserted island; after Ethel wanders around a little, Lucy notices huge footprints in the sand she deduces belong to a giant native, and proceeds to follow them, only to find they're Ethel's.

However if the lead ant gets lost and walks around back to the original trail laid down it'll just keep walking in that circle.
