One day, five and twenty convicts...

There's a problem with the visitor counter and it's decided it's my problem.

"It's stuck. It won't move past '21'"

I have a look at the counter. It says 5221. I do my quick impression of the Trooping of the Colour and yes, it still says 21: 8221.

I take it off the wall and put it back on the right way up: 1228
