CBS's Thursday night line-up is all new tonight, which means a new episode of The Big Bang Theory. Sheldon continues to put tiring, selfish and unreasonable demands on Leonard's time, which leads Leonard to question whether they should continue to be friend.
Meanwhile, Wolowitz shows his friend the announcement about his upcoming space flight and Koothrappali remarks that he's the only member of the group without a "cool" astronaut nickname. Wolowitz says that it's a big faux-pas to pick your own name and it should be chosen by your fellow astronauts. Also, there's a wicked-awesome lightsaber.
Watch a sneak peek below for tonight's all new episode of The Big Bang Theory, airing at 8:00 p.m. EST on CBS. You can also use the arrows above to browse through photos. Tonight's episode is set to run an extra minute long, so make sure to adjust your DVR accordingly.
