There's a fine line between the sublime and the ridiculous. Jack has no idea where it is but enjoys finding out with wordplay, puns and nonsense teetering on the border between daft and dafter. A show packed full of jokes. Silly jokes. Risqué jokes. Downright ludicrous jokes. And a healthy dollop of visual gags, not very musical interludes, a language lesson, and as a final feature a foray into meta-madcappery.
