Craig Ferguson to Tina Fey: Twitter isn't like heroin... except in one way [Video]

If you’re a 30 Rock fan, you likely already know that Tina Fey doesn’t have a Twitter account. And while on “The Late Late Show” with Craig Ferguson this week, she told the audience why: she’s afraid she’ll become addicted. But, interjects Ferguson, Twitter isn’t like heroin – except you might fall asleep on the sidewalk while tweeting. Check out this funny clip below.

Fey was on Ferguson’s show promoting her new book “Bossypants”, which Ferguson told her was just a really, really long tweet.
