David Lee Roth may be 56 years old, but that doesn't mean that he's not still kicking ass.  At a show in New Hampshire on Tuesday night he interrupted '(Oh)Pretty Woman' to let a couple of people in the crowd know that fighting is not cool.  Warning, NSFW language.

Guess what people, mosh pits are not acceptable at every show. Personally, I am not a fan of them and never have been. David Lee Roth is just the next rock guy to stand up for the fans that don't want to be pushed around by some meat head. Dave Grohl of the Foo Fighters kicked a guy out of a show not to long ago for fighting.

So if you're going to mosh, make sure it's socially acceptable first. You don't want to end up like this guy. Props to DLR for sticking up for the fans.
