The great news keeps rolling in for The Big Bang Theory: it's best ever ratings this past Monday and now this: Terminator: The Sarah Connor Chronicles' Summer Glau will be guest starring on the March 9th episode!
The plot setup (courtesy of EW):
"A train trip to San Francisco takes a major detour when Leonard, Sheldon, Wolowitz, and Raj discover that their favorite sci-fi actress in all the land is on board. But the fanboy frenzy quickly gives way to a heated mass debate (tee-hee) when they realize one of them will have to approach her - but who?"
Should be a fun episode!
