The joke behind this clip is one of gaming culture's most durable memes: that Valve, the studio behind Half-Life, Portal, Team Fortress and Left 4 Dead, never makes a third installment. For years fans have turned Half-Life 3 into shorthand for vaporware, spawning countless jokes, videos and songs about the missing threequel. Short musical takes on the gag circulate widely because they compress the whole reference into a few seconds. This version follows that tradition, made to be shared between friends who instantly recognize the punchline.
