Mike Tyson's Punch-Out was all about timing and rhythm, and every fighter had a secret pattern which Little Mac could use to take down fighters five time his size, even the legendary Mike Tyson.
Getting the rhythms down meant memorizing every fighter's moves, but nearly thirty years after its release a Redditor named midwesternhousewives discovered a better way to beat each fighter- by looking to the bearded guy in the audience.
In the front row of the crowd about six heads from the left is a little bearded guy who ducks down when Little Mac should punch Piston Honda and finish him off.
This Easter Egg also works against Bald Bull, and back in 2009 late Nintendo president Satoru Iwata admitted there was also a camera flash cue in the crowd to tell players when to throw the knockout punch.
