It seems like there is always one guy at every rock show who just doesn't play well with others. While the rest of the crowd is dancing and trying to have a good time, there will always be one guy kicking the air and throwing random hay-makers.

This is how fights tend to start and Dave Grohl doesn't tolerate this kind of behavior at his shows.

When Grohl spots a striped-shirt wearing troublemaker starting a fight in the pit at Tuesday night's iTunes festival gig in London, he decides to stop his show and curse the guy out. Dave Grohl doesn't have to fight. He uses his sNSFW words to neutralize the situation.

"You don't f***** fight at my show you a******. Let me see him, who's fighting right now? It's that guy in the striped shirt. Hey mother****** look at me, get the f*** out of my show right now. I don't put up with that bull**** -- you people came here to have a good time and that guy can f*** off."

Way to tell it like it is, Dave. Check out the video below, along with Grohl's very un-family-friendly language.
