Big Bang Theory and D&D

I watch the show Big Bang Theory when I can because of all the GeekSpeak found on the program. While I enjoy the show, I can not BELIEVE that Sheldon and his buddies have not engaged in a Dungeons & Dragons edition war yet. There is no way that these characters know as much as they do about all things geeky, from comics to Star Wars to Star Trek, and they have never played D&D?

Well, I for one want my BBT D&D episode! Who at CBS do I yell at to get this done? :D
