There's an old Comic Relief one too, don't know if it's of interest: Can't Smeg, Won't Smeg, where they have to try to cook or something? Might be worth checking out. Also The Smeg-Ups, though I'm sure you know about those. I assume you have all the books too?

Incidentally, I don't know if it would be of interest, but you know Chris Barrie stars in The Brittas Empire, basically almost reprising his Rimmer character, except more annoying? Well worth watching.
