Case in point, when I first watched ITYSL, I remembered TR as "the weird guy that was on SNL for like 5 minutes". I remembered that I always thought he was really really weird in his sketches. I didn't think they were bad but just like "wow I don't get this guy's humor".
Now I go back and watch them and I think they are hilarious, and it makes total sense that some of the basis of his skits started as ideas for SNL bits. Lorne Michaels told TR that his stuff was good but just not right for SNL, and I'm glad he stuck with backing TR.
