Bisping Flips someone off during weigh ins

At the UFC 110 weigh ins just a few hours ago, Michael Bisping weighed in before Wanderlei Silva and flips someone off while on the scale after his weight was announced. Who could he be flipping off? Wanderlei was still back stage, and it appeared to be a joke because he laughed, but the question still remains-who was he flipping off?! Hopefully someone interviews him and asks about this. But the weigh ins for the co main event gave us a preview of the entertainment this fight will provide (Dana had to hold back Wanderlei during the staredown).
