A question for whoever knows who do the voices

Dec 15, 2012
I was wondering if Gilbert Gottfried does Ratbeard's voice and I was also wondering who does Kobe Yojimbo's voice, at first I thought it was Patrick Stewart but my dad heard the voice and said it definitely wasn't Patrick's. If so then I was wondering who has a deeper voice than Mr. Stewart?! I'm pretty sure about Mr. Gottfried doing Ratbeard's though.
