Earlier last month, someone filmed a video of this guy singing to 'Livin' on a Prayer' by Bon Jovi all by himself.
As he hits the chorus, the entire crowd at the park joins in... "Woah, we're half way there, Woah, livin' on a prayer!"
"This might be the closest humanity has gotten towards world peace." one viewer said.
"All it takes is one person to move the masses towards good. Be that one person in the world!" gushed another.
