Tonight on The Big Bang Theory, Sheldon (Jim Parsons) meets up with his nemesis: Wil Wheaton.

I have managed to get in the Big Bang Theory habit this season in spite of CBS's attempts to make it difficult, and I am atwitter for that reason about tonight's episode.

Tonight, Sheldon meets Wheaton.

Wil Wheaton has managed one of the most remarkable transformations in pop-culture history, from the most hated twerp of the Star Trek fandom (he played Wesley Crusher on Star Trek: The Next Generation) to a funny, self-deprecating, tech-savvy writer and Master Of The Social Media Universe. Finding people who don't like Wil Wheaton these days is like finding people who don't like Neil Patrick Harris: they're out there, absolutely, but you really, really have to be looking.

Much of that has to do with Wheaton's witty, relaxed way of both embracing and escaping his Star Trek past, and that's what brings him to The Big Bang Theory. On tonight's episode, Sheldon (Jim Parsons) has a bone to pick with Wheaton, and if you know who's going to come out ahead in that clash of the nerd titans, you're ahead of me. I just want to see it.
