Duke Nukem 3D was released in 1996 by 3D Realms and became known for its wisecracking hero, voiced by Jon St. John. Come Get Some was one of Duke's recurring one liners and also the name of a difficulty level in the game. As clips and ports kept the game in circulation, the line spread into forums, machinima and meme edits as a shorthand for a confident challenge. Its short length and unmistakable delivery keep it useful long after the original release.
