Some of the tangents can be. I don't mind them having a discussion about moments in their lives that turned out to be decisive during the Dimension Jump podcast, because it's related to the episode's concept. But it's the completely unrelated ones that annoy me. That one you mentioned about Bill and Ted for instance doesn't relate to Red Dwarf at all, and so should have been cut (What is with their Bill and Ted obsession anyway? It's an awful couple of movies). They frequently laugh about how far off-topic they've become. I keep thinking that if they have enough awareness to know that they're constantly going off-topic, then they should realise they need to stop doing it.
