Post-DNA radio versions
I find the post-DNA radio versions all a bit flat in comparison. DNA managed to instil a curious type of almost-science, and relentless logic, into it that sort of made sense, as well as being funny. The newer ones seem to be more focused on inventing characters whose names are generated in a way reminiscent of the originals. There's nothing like the SEP field, or Bistromathics, in the recent ones.
