Bazinga! The geniuses are back, and the stakes are getting higher in both the lab and relationships.
The Big Bang Theory continues with a sixth season that takes nerdy humor to a whole new level – literally! The season begins on a high note as Howard Wolowitz ( Simon Helberg ) finds himself (or is) thrust into space on the International Space Station, leaving Bernadette waiting on Earth.
Meanwhile, Leonard ( Johnny Galecki ) and Penny's ( Kaley Cuoco ) relationship finds new ground, and the series' absolute star Sheldon Cooper ( Jim Parsons ) tries to get creative in his relationship with Amy Farrah Fowler - with his own, very special rules, of course. Raj also experiences big changes during the season when he meets the shyest of the shy Lucy.
