From the 1993 western film, Tombstone. Johnny Ringo and Doc Holliday had a few run-ins before their duel at the end of the film. The Earp brothers settled in Tombstone, Arizona Territory and took up a position in a local saloon. Wyatt meets up with his old friend, Doc Holliday who is suffering from tuberculosis and needs the dry air.

In the first scene, the ruthless western gang, the Cowboys and their leader Curly Bill show up at the Earp's saloon. Johnny Ringo recognizes Doc and asks him if he's retired, too. Clearly, Doc is not "in his prime" but he says he is. Doc recognizes that Ringo is a loudmouth showoff, but the fact that he is an educated loudmouth showoff makes Doc loathe him.

In the second scene Ringo is stumbling around Tombstone drunk. He challenges the Earp's to a blood duel, which they refuse. Doc then issues the most remembered line from the movie, "I'm your huckleberry." Curly Bill manages to wrest Ringo away from a sure death at the hands of Doc.

In the final scene, Curly Bill has been killed by the Earp posse and Ringo takes over leadership of the Cowboys. He challenges Wyatt to a one-on-one duel to end the blood feud, which Wyatt accepts. Little does he know that Doc has beaten him to the meeting place. Doc and Ringo then finish their challenges.

The official script for Tombstone has Doc Holliday's line as "I'm your huckleberry" which is a take on the slang "I'm your huckel bearer" or "I'm your pall bearer."
