Inventive and always joking, physicists Leonard Hofstadter (Johnny Galecki) and Sheldon Cooper (Jim Parsons) live in a reality of their own, still trying to adapt to a world that, apparently, they do not quite understand. The intelligence of the two contrasts sharply with the sociability and star veils of their gorgeous neighbor, Penny (Kaley Cuoco), hence a series of downright funny happenings in a comedy that should not be missed.
