The line comes from Smokey and the Bandit, the 1977 action comedy starring Burt Reynolds and Jackie Gleason as Sheriff Buford T. Justice. In a roadside diner scene, the impatient sheriff barks his order for a Diablo sandwich and a Dr Pepper, a moment fans have quoted for decades. Clips of Gleason's performance circulate widely on soundboards and meme pages because the delivery is instantly recognizable. It endures as shorthand for Southern bluster and comically urgent hunger, especially in edits about fast food and road trips.
