How many fingers am I holding up?

That's just Jim dandy that is: the people counters that have been installed in all our libraries have no moving parts, but we found last week that they can stick somehow (!!!) and three weeks' worth of stats for Noddy are lost forever; now we find that resetting the counter by pulling the plug isn't reliable either. T.Aldous discovers that giving the counter a vigorous shake and calling it "you sod" seems to do the trick.

"I didn't want to buy this model," he tells me.

For once I sympathise.
