THE BIG BANG THEORY
CBS, 8:00 p.m. ET
Ask yourself: Could this sitcom get any geekier? Then tell yourself: Yes, it could, and tonight, it does. Making return appearances are two alumni from Star Trek: The Next Generation. One is Wil Wheaton, as an arrogant version of himself who is the long-time nemesis of Sheldon (Jim Parsons). The other is LeVar Burton. And in this very same episode, Wolowitz (Simon Helberg) finally moves out of his mom’s basement. Once you’ve been to outer space, as astronaut Wolowitz has, I guess you just need more… space.
