Just to keep up the penguin quotient here, a short but rather charming documentary about penguins - to be taken with a large pinch of salt of course, as it was released yesterday:

- look now, as the clip will only be there for a few more days.

Can't do iPlayer from here, but I'll try from home later. There was an episode of the Simpsons once where Lisa was in a zoo or something after hours, and was horrified to discover the penguins flying round their enclosure when they thought nobody was looking.
