"The Big Bang Theory" exec producer Bill Prady got a reminder from CBS today: You do your job, and we'll do ours.

The issue: A Tweet that Prady sent out early Tuesday:

Now granted, Prady is right. Sept. 23 is the first Thursday of the new TV season, so clearly, that's the date on which "The Big Bang Theory" — now on Thursdays — will launch its new season.

The problem: It's not actually locked in. CBS scheduling guru Kelly Kahl reminded him that nothing was official yet — via a Tweet.

(You may remember, Prady also prematurely congratulated Shawn Ryan via Tweet on his "Ride-Along" pickup — even though it hadn't happened yet. Thankfully, it did, a day later.)
