With the company's stock price in long decline, it's hardly a surprise.
But we'd like to take a look at Mason's weirder, more lighthearted side.
Groupon established itself early on as a quirky, humorous company, and it seems to stem from Mason's own personality.
In this Wall Street Journal interview, he was asked if he's mature enough to run the company. We loved his response:
"I was weird before we were a public company and managed to get it worth whatever it's worth. I'm going to continue doing my thing and work my butt off to add value for shareholders and as long as they and the board see fit to keep me in this role, I feel enormously privileged to serve."
