I have a vague memory of an episode that I saw once, and only once, as a kid. The episode featured Larry, Daryl & Daryl fairly prominently. I remember that for some reason, Dick went over to LD&D's house for what I believe was the first time in the history of the series. When Dick got there, instead of finding a rundown shack as you might imagine. LD&D where living in a rather opulent mansion-like home. As Dick entered, he saw one (or possibly both) Daryl(s) sitting behind a Grand Piano playing some classical piece.
Unfortunately, that's all I can remember of the episode. I'm sorry that I can't give you any more to go on here. Hopefully though, somebody will know what I'm talking about.
