naughty dialogue

I just spotted John Gilbert swearing. At about 36:12 as he's angrily approaching Salome it looks like he said "you G.D. b_tch." I have heard actors would say things that their character might and were called out by lip readers. I'm 99% sure that's what he said because that's exactly how his character was feeling at the time. It was such a different time in so many ways, but just the same in others.
