There was a Kings of Leon show fairly recently, one of the major festivals in the UK I think it was, where Caleb got pretty p.o. at the crowd not being as into it as he felt they should have been. There was professional video of it, I think, and someone took the liberty of editing it into this video, which I personally find hysterical.
The thing about this is while I don't like the idea of band members dressing down huge crowds of people, especially when it's such a generalized statement, when it comes to people only showing up to Kings of Leon shows to hear "Sex on Fire", I kinda agree. Oops.
