They're coming down the stairs...

You know those word games that sometimes start up, and before you know where you are your brain has been wholly sucked into them, and you can't stop ? A good example is the telling of fish related jokes - a couple of weeks ago at a fish restaurant we got into a rut where no one could break away from them. Everytime we declared an intention to stop it, there'd be a small, guilty sounding voice cracking another one.

We found another one last night.
