The clip comes from Half-Life, released by Valve in 1998, where the security guards at Black Mesa were all based on a character model nicknamed Barney. The guard later became Barney Calhoun, the lead of the 2001 expansion Half-Life: Blue Shift and a major ally in Half-Life 2. His short NPC barks were ripped from the game files and shared on soundboards and in Source engine memes, Garry's Mod videos and gaming edits, where the instantly recognisable voice still signals classic PC gaming nostalgia.
