It looks like producers of television's geekiest show (after 'Face the Nation,' I mean), 'The Big Bang Theory,' were happy with Wil Wheaton's guest appearance a while back because they have invited him to do the show once again. The show got a big ratings boost when our old friend played Sheldon's enemy on the show earlier this season, which was funny because he was playing himself.
He calls himself "evil Wil Wheaton." He got the official word this morning that the episode is a go and he'll tape it on March 2. If this turns into a semi-regular thing, where he returns to the show every once in a great while to torment Sheldon, they should have a surprise other cast member from 'Star Trek: The Next Generation' to come on and challenge Wheaton or get in the middle of things. I can picture Jonathan Frakes or Brent Spiner doing that.
