I remember accidentally bumping into this on Channel 4 (I must have been fifteen or something), and thinking "What is this low budget pap?". I must have bumped into it a few more times and suddenly the penny dropped. This truly is some of the best comedy I've ever witnessed. It's pretty unique, and if you've not already had it, it may take a few episodes before you have your "Eureka" moment, but when you do, it really is fantastic. Like the other reviewers here, I'd suggest this is probably the cream of Vic and Bob's work so far, although perhaps the least accessible.
I'm guessing that most people reading this probably already know that they love this series, so perhaps a little info about the DVDs themselves. It's stashed on two DVDs (not crammed onto one or anything), so the picture quality is everything it should be. There's only really one extra, and that's a nice little interview by Matt Lucas (seen as George Dawes on Shooting Stars, and star of Little Britain), which is dead interesting and reasonably long. The entire first and second series are present, but unfortunately the New Years Eve special (or maybe it was Christmas, I dunno) featuring Kim Wilde is missing.
As you might guess, I'd totally recommend this - I regard it as an extraordinarily significant step in the history of British commedy (which unfortunately most people don't seem to have latched onto), and if I need to cheer myself up, this is likely to be the DVD I reach for. Either that, or the Mighty Boosh. Hey - why not buy 'em both? I did. They're well spanky.
