Penny Smith (I)

Despite being a fully-fledged member of the Grumpies' fan club I bet narrator Geoffrey Palmer and his gang of grouchy celebs are the Christmas guests from hell.

Ronni Ancona will moan that your Jamie Oliver-inspired turkey and cranberry sauce is "basically chicken with jam", Al Murray will tell you to "go away" when you talk to him about the joy of giving (he actually uses stronger language but I'm starting my New Year's resolution a few days early) and Penny Smith will moan that it's all "sentimental claptrap". Donna McPhail will terrify your dog by declaring Christmas is "worse than a puppy because you can't put it in a sack and drown it." And Ozzy Osbourne will consider getting back on his quad bike to avoid the whole thing for a second time. It's "just b******s," he says. Oh damn, there goes my resolution already.
