What Pixar television short series features Mater telling exaggerated stories in the Cars universe?

Mater's Tall Tales is the Pixar short series in which Mater tells exaggerated stories.

The series debuted in 2008 as Cars Toons: Mater's Tall Tales. Each short presents Mater claiming that he participated in an extraordinary event, often involving famous occupations, dangerous missions, or spectacular adventures. Lightning McQueen usually questions the story, but the events then appear to have happened in the cartoon's playful reality.

The first three shorts premiered on television in October 2008. The series expanded the Cars universe beyond the feature films and gave Mater a leading role in short-form comedy. Cars Toons is the umbrella branding, while Mater's Tall Tales is the specific title associated with the storytelling format. It should not be confused with Cars on the Road, a later Disney+ series featuring Lightning and Mater.
