Have to agree it was disappointing. For me, the sketch that was the biggest let down (perhaps due to its hype?) was ting tong. If that passes for classic comedy, give me Little and Large instead. And I assume Walliams has used up his quota of new voices.
Incontinent old lady was also weak, we already have the Tory lady chucking up which offers a similar vein of humour but is far funnier and cleverer.
On the plus side (and to prove I'm not just going for high brow) the naked wrestling between Bubbles and her love rival in the first episode was classic, rounded off by a good one-liner from Brydon.
