Which Pixar Cars short-film series features Mater telling exaggerated stories about himself?

Mater’s Tall Tales is the Pixar Cars short-film series in which Mater tells exaggerated stories about himself.

The series is part of Cars Toons and began with short episodes released in 2008. Each story presents Mater claiming to have played a remarkable role in an adventure, such as working as a firefighter, a rock star or an astronaut. Lightning McQueen often appears as a listener or participant, and the shorts deliberately blur the line between Mater’s storytelling and what may really have happened.

The humor comes from Mater’s confidence and from the increasingly unlikely details of his memories. The title refers to “tall tales,” a traditional term for extravagant stories that stretch credibility. Mater’s Tall Tales is separate from the three feature films and from the later Cars on the Road series, which follows Mater and McQueen on a road trip.
