The Big Bang Theory  tells the story of two roommates, Leonard (Johnny Galecki) and Sheldon (Jim Parsons), two brilliant physicists with the kind of “beautiful minds” that understand how the universe works, but have no clue when it comes to social interaction with the opposite sex.  All this begins to change when a free-spirited beauty named Penny (Kaley Cuoco) moves in next door.  Sheldon is quite content spending his nights playing board games with their socially dysfunctional friends and fellow scientists.  Leonard, however, sees a whole new universe of possibilities in Penny; one of them being true love.>
