Wild Bill
Does anyone else wonder if Bill's whole demeanour might be put on?
Occasionally when he's talking either to camera or just in conversation with the others it sounds like he slips into a normal (relatively speaking) voice for a few words. Almost like he forgets to do the exaggerated voice and then quickly corrects it.
Maybe I'm just hearing things, but there are times when I think that on-screen persona is not his real voice.
