Every single act in this compilation walked onto that stage and gave four judges exactly one thing to work with before the performance even started. A first impression. The way they looked. The way they carried themselves. The way they stood in front of that microphone or that instrument or that empty stage. Four judges who had spent their entire careers trusting their instincts formed an opinion in seconds. Then every single act performed. And one by one every single judge in this compilation discovered the single most important lesson that twenty years of experience had somehow still not taught them. Never trust first impressions. Not one of them learned it easily. Every single one of them found out why the hard way. Watch every single moment that taught them that lesson permanently. 0:00 Andrew De Leon - AGT 2012 S7 4:39 Tape Face - AGT 2016 S11 9:51 Gruffydd Wyn - BGT 18:34 Simone Battle - The X Factor USA 2011 S1 22:47 Puddles Pity Party - AGT 2017 S12 28:04 Neal E.
