Yes, that's right. Today is actually National Grammar Day!!! (Well, it is in the US, at least). It is imperative we raise a glass to gerunds and infinitives, congratulate the conditionals and send a mazel tov to all the main verbs who agree with their subjects. You can read more about National Grammar Day here.
So, in homage to National Grammar Day (which I believe should be International Grammar Day!), enjoy this 'classic' grammar lesson from Monty Python's Life of Brian.
