The line comes from Deus Ex, the 2000 action role playing game where JC Denton is the augmented protagonist. Denton is known for his monotone, deadpan delivery, and short clips of his dialogue have circulated for years in gaming forums, edits and soundboards. This phrase became a reusable reaction because it captures that dry style in a single second, separate from any longer scene. It remains popular with players who quote Denton lines as memes and drop them into multiplayer clips and parody videos.
