This is a good list of 10 great episodes. I'd have added Marooned personally, but I can't argue with this selection.

What would you add?
I'd agree with Gunmen Of The Apocalypse and Back To Life. Those seem to be a lot of people's two favourite episodes. Not sure if I agree with Tikka To Ride. Though, that might just have been based on my confusion as to how they used the time drive to get them back to Earth, whereas in the previous episode that hadn't worked.
Then again, since when did Red Dwarf bother about continuity.
