I would sit there eating a bagel for the first 4 minutes, starring directly at him. Then I would ask him what kind of music he likes, if he says Pop or Rap, then I will ask him one question about a famous classic rock artist and if he answers incorrectly then...well...I would beat him down and then leave.
Lol at the people saying they'd kill him/beat him up. That won't prove anything. It'll only prove that you're messed up in the head, and probably need therapy or that you belong in a mental hospital. As for me, I would just sit down and have a talk with him. A talk about how he feels about all of this criticism and all of these death threats he's getting. And I would also ask him about what he does to block it out. And then after 5 minutes I would get up, shake his hand, and leave, like a "civilized" person would do.
Lol, why does everyone keep saying they wanna beat him up? I see it this way: 50% of the people don't care about him. 40% of the poeple pretend they hate him because they think it's "cool". 10% of the people actually hate him.
I would get his autograph and sell it on the internet.
You didn't copy anyone idontsuckthatmuch. And if I had 5 minutes with Justin Bieber I would probably just say hi and leave. Not much else to do. He isn't that great to me.
