"So I showed up with 15 strippers" . The ability to laugh at ourselves is key. Derek is a man of character not in spite of his experiences, but because of them. Lesson learned.
Just goes to show that there are different levels of human. Not everyone is created equal no matter how much we try to pretend otherwise. On the other hand, you can still work just as hard and push your own limits just as far and be a better person for it. This series is so great.
