Is that the Squire of Gothos?
No, but the voice, mannerisms and fondness for tacky decor are quite similar. Hadn't thought of that before.
Was glad someone caught that. I always assumed the Squire was supposed to be a Liberace ripoff.
Also, after some quick wiki’ing, just realized he is the same guy as the Klingon Koloth. "Ah, my dear Captain Kirk!"
