You can't believe it. You're enjoying yourself. You've been having a great day. You've been working pretty much non-stop, but it's not been overwhelmingly busy. You're patients have been nice and courteous and they've mostly all been interesting cases. Your clinical acumen is sharp today and you've missed nothing. You're especially proud of that thoracotomy you did in the men's washroom with a fountain pen and your pocket rib spreader.

Hang on - you don't have a fountain pen. You wake up and fall off the trolley you had dozed off on, into a pile of something on the floor that worryingly seems to contain diced carrots.
