Mad as a Mars Hare is a 1963 Warner Bros. Merrie Melodies cartoon directed by Chuck Jones and Maurice Noble.

Bugs, upon landing, symbolically claims Mars for Earth with a flag-bearing metal carrot, provoking Marvin's vehement objection to relinquishing his planet.

Undeterred, Marvin employs a Time-Space Gun to project Bugs into the future as a subservient laborer.

Bugs, unfazed by the ordeal, addresses the audience, musing about surprising Earth's hunters upon his return, before nonchalantly consuming the metal carrot.

The full-screen version is available on the Looney Tunes Platinum Collection: Volume 1 Blu-ray box set and its DVD edition.
