Murray is the strongman hippo of the Cooper Gang in Sly Cooper, the PlayStation platformer series from Sucker Punch that began in 2002. The phrase kan bare en sang is Norwegian and Danish for can only manage one song, turning a tough sidekick into a one song joke. Clips like this circulate in gaming soundboards and short edits because the line is self contained and instantly understood even without the original scene, and fans reuse it whenever someone repeats themselves.
