I am pretty sure that you have seen people holding up signs and different events either a concert of a wrestling match. But what happens when the sign gets acknowledged and you are asked to get up on stage.

For 13 year old Anthony Potenza, this exactly what happened when he went to go see Machine Head in concert. He was holding a sign that said "Let This 13-Year-Old Play 'Aesthetics of Hate' With You," and Machine Head brought him on stage with them.

Check out the video and start bringing signs to concerts cause you never know when you'll get called upon!
