The line comes from The Armstrong and Miller Show, the British sketch series starring Alexander Armstrong and Ben Miller that aired in the late 2000s. The deadpan kill them delivery became a quotable moment that fans clipped and shared as short audio. It spread through meme pages and gaming edits, where the polite but ruthless tone made it a natural punchline for betrayals, boss fights and ruthless decisions. It remains in use because the contrast between the calm voice and the violent words keeps working as dark comedy.
