"Big Bang Theory" executive producer Bill Prady and guest star Wil Wheaton conspired to see how a Twitter message campaign could help last night's episode of the CBS comedy, in which Wheaton appeared as himself.

The answer is quite a lot. According to The Wrap, "Bang" scored a 3.9/10 in adults 18-34 demo, up 15% from last week's episode. Preliminary overnight Nielsens for total viewers show that "Bang" might wind up with its best ratings ever.
