Don't EVER throw anything at Lil Wayne while he's on stage. I think his audience learned that the hard way.
He threatened them with guns after someone threw a water bottle onstage. Weezy was performing at the Jumanji Festival in Sydney over the weekend, where all seemed fine until he was almost hit by a flying water bottle. That's when he stopped the show to warn the audience about that would happen the next time someone violated him.
