Whatever you think about Andrew Mason’s abruptly snuffed out run as CEO of Groupon, you have to give him this: He has just set the gold standard for farewell letters.

“After four and a half intense and wonderful years as CEO of Groupon, I’ve decided that I’d like to spend more time with my family. Just kidding — I was fired today.

Nicely done, Mr. Mason.

People of Groupon,

After four and a half intense and wonderful years as CEO of Groupon, I’ve decided that I’d like to spend more time with my family. Just kidding – I was fired today. If you’re wondering why … you haven’t been paying attention. From controversial metrics in our S1 to our material weakness to two quarters of missing our own expectations and a stock price that’s hovering around one quarter of our listing price, the events of the last year and a half speak for themselves. As CEO, I am accountable.

You are doing amazing things at Groupon, and you deserve the outside world to give you a second chance. I’m getting in the way of that. A fresh CEO earns you that chance. The board is aligned behind the strategy we’ve shared over the last few months, and I’ve never seen you working together more effectively as a global company – it’s time to give Groupon a relief valve from the public noise.

For those who are concerned about me, please don’t be – I love Groupon, and I’m terribly proud of what we’ve created. I’m OK with having failed at this part of the journey. If Groupon was Battletoads, it would be like I made it all the way to the Terra Tubes without dying on my first ever play through. I am so lucky to have had the opportunity to take the company this far with all of you. I’ll now take some time to decompress (FYI I’m looking for a good fat camp to lose my Groupon 40, if anyone has a suggestion), and then maybe I’ll figure out how to channel this experience into something productive.

If there’s one piece of wisdom that this simple pilgrim would like to impart upon you: have the courage to start with the customer. My biggest regrets are the moments that I let a lack of data override my intuition on what’s best for our customers. This leadership change gives you some breathing room to break bad habits and deliver sustainable customer happiness – don’t waste the opportunity!

Andrew Mason
