This. Entirely this.
If they had just gone "woo hoo we're on the TV thing at a concert! Woohoo" .... Like everyone expected them to, then nobody would have given a shit.
They're just people having fun at a concert.
Meanwhile, they freaked the fuck out, the guys on stage pointed it out, and everyone went full Psycho trying to figure out what was going on. And now they're in the daily dose of Internet.
GG guys. Ĝis poste
Super fun fact, the people who aren't idiots at the self checkout, are not notable and therefore are not noted. It's the morons who stand out.
Just like with driving. The guy in front is always too slow, and the guy behind is always going too fast. Because you don't notice when the inverse is true.
