I've been rewatching This Time... on iPlayer this week and /controversial view, but I think it's as good as anything he's ever done. There's so much that should go down as classic Partridge - his face being superimposed onto a small child's then showing the viewer the correct way to dish our corporal punishment, the whole John Baskell scandal, Alan becoming more and more camp during the fashion segment, anything with Sidekick Simon.
It might be because I was quite late to the latch onto Partridge but it's as funny as some of the stuff in I'm Alan Partridge series 1.
