The thing is, besides being an utter toad of a human being, Riedel usually has the least knowledge of the topic in the room. He doesn't usually understand the content or approach of a show, and is always completely and unfailingly socially ignorant, which makes it really infuriating when Susan can't get a word in edgewise. A definitive mansplainer; it's always painful when he has female guests. I watch the show sporadically when I really want to see a guest, because it's the only theatre talkshow we have, but it would be so much better without this hateful clown in a dadcoat.
