If you have a few minutes during the holiday week, check out Rich Eisen’s podcast with Twitter CEO Dick Costolo.

Among other things, you learn that if Costolo had been a better stand-up comic, the world may never get Twitter. After graduating Michigan, he joined a Second City training program in Chicago that included a young fellow named Steve Carell. Wonder what ever happened to him?

Thankfully for Tweeters everywhere, Costolo’s life took another course. Now your life isn’t the same.

The rundown from Eisen’s site:

It’s a special late-week edition of The Rich Eisen Podcast featuring the CEO of Twitter, Dick Costolo. Eisen and his fellow University of Michigan alumnus discuss all things Twitter and the incredible impact that it has had not only in sports, but in our daily lives over the past few years. The hour long conversation hits on a myriad of topics, but none more important than Eisen’s request for Twitter to implement a sarcastic font, a.k.a. the “Eisen Font,” and for producers Chris Law and Chris Brockman to get blue check marks.  Costolo’s responses to both are priceless and spawned this week’s #REP Poll Question, so be sure to vote.
