good gracious, we're still discussing this?
Well actually, until you bumped it after 8 hours of no one replying, we weren't discussing it.

It's a pointless discussion. Justin adlibs during concert performances of CMAR, he always has and most likely always will. It's part of the performance. Don't like it, don't go to the concerts, end of story. Whining by Britney fans about what a horrible person Justin is for expressing himself is pointless because it won't change a thing. It's one song out of many, it's just not that big of a deal.
