I think the best way to sum up 'Scrubs' is to say that it is the only show I know where you actually miss half the jokes because you're still laughing hysterically from the ones before. Series 4 is possibly the weakest up till now, but is still worthy of five stars any day of the week. Perhaps the funniest moments, as ever, come from the Janitor who in this series interacts with a lot more characters besides JD (and some squirrels). Some new characters are also introduced, including my new favourite - Hooch. Whatever issues are being tackled in Scrubs, there is never a dull moment, and Series 4 is only slightly less terrific than the three before it.
