I wish I could do this

I had this happen today in a meeting I weas facilitating. We are in the middle of trying to figure out a relatively complex problem we are dealing with and this freakin chowderhead's phone rings. Expecting that he would silence the phone and continue as part of the meeting, I was shocked when he answered the phone and began a conversation. I was particularily pissed off when he gave me the index finger quiet sign when I asked him to can the call. At that point, I could have used the Dark Side of the Force to pop this fucker's head off.
