Write out a hundred times: I must not play Calvinball in the office.

My colleague is babysitting his niece this week, which means we've got a seven-year-old in the office today. I've totally found my level. So far today we've played 'how fast will the office chair spin?', 'Use the office chair as a chariot down the corridor', and 'Mousemats as ninja stars across the office'.

I'm not expecting much work to get done round here for the rest of the day either.
