Summer Glau herself is stopping by and blowing the minds of our fellow nerds on Big Bang Theory, on March 9, according to Entertainment Weekly's Michael Ausiello. The set up is this: "A train trip to San Francisco takes a major detour when Leonard, Sheldon, Wolowitz, and Raj discover that their favorite scifi actress in all the land is on board. But the fanboy frenzy quickly gives way to a heated mass debate when they realize one of them will have to approach her - but who?" The only thing better than a nerdy crossover is a crossover featuring Summer Glau. I hope someone gets her number. [Entertainment Weekly]
