Don't cross these musicians, because they'll single you out in a crowd. These moments were all caught on film, and we wouldn’t be surprised if these fans never bought tickets to a show again.

Don’t hold up a photo of Kurt Cobain if you’re going to see Courtney Love live. The Hole frontwoman freaked out on a fan who did just that, giving them a lesson on boundaries. “I’m not Kurt. I have to live with his fucking shit and his ghost and his kid everyday,” Love said. “Throwing that up is stupid and rude, and I’m gonna beat the fuck out of you if you do it again.”

Love invoked Dave Grohl’s name during her rant, and the Foo Fighters frontman has done his fair share of crowd control. At the 2011 iTunes Festival, Grohl kicked out a fan in what’s now a viral video. “You don’t fucking fight at my show, you asshole,” Grohl said after stopping the gig. “Get the fuck out of my show right now. You don’t come to my show and fight, you come to my show and fucking dance, you asshole.”

In the history of rock, there may be no more vicious callout than Josh Homme at Norwegian Wood 2008. Suffering from a 102 degree fever, the QOTSA frontman saw red after getting something thrown his way. Homme sounded like he wanted to kill the young man, but instead settled on throwing a bottle of water at his face. “Go back to your mom’s house, you 12-year-old dickless fucking turd,” Homme said while security led the fan off.
