Wil Wheaton is returning to The Big Bang Theory.

Sorry, Evil Wil Wheaton is returning to The Big Bang Theory.

The Star Trek: The Next Generation first played a jerky version of himself in October, and is slated to do so again on an episode that airs in April.

Regarding his reprisal as Sheldon's nemesis, Wheaton blogged this week:

"Even though my personal motto is Don't Be A D**k, I've wanted to play an arch enemy for pretty much my entire career, and I love that ['Big Bang Theory' co-creator] Bill [Prady] described me that way, because I was kind of hoping I'd earn that position in the 'Big Bang' canon."

He has, indeed. Below, we've posted a snippet of Wheaton's first stint on the sitcom:
