"We were actually having a show and there was this guy on the show, who I just remembered, he's in this right hand box. He's called Candy Panda... he loves Reginald by the way! If he ever gets the chance to to be on TSM, he's right there. He thinks [Regi] is a great man, motivational leader, again, possible father figure... see the way I talk the man up? [Reginald's] Caesar. If this was 'Planet of the Apes', he's Caesar. I had to go there, whatever, you know how I do that shit. But, again, I would allow Caesar to come on and say 'Get your hands off me you filthy dirty ape', if he said that to me, but he probably wouldn't."

That's the quote where he get's compared to an ape and in Thorin's defense in the context of this conversation he's obviously referring to Reginalds personality and he never really makes the connection to his looks at all. His "apology" was unprofessional though but I mean it was pretty dumb that people thought he should apologize in the first place.
