The Big Bang Theory - Show Summary

Leonard and Sheldon are brilliant physicists, the kind of "beautiful minds" that understand how the universe works. But none of that genius helps them interact with people, especially women. All this begins to change when a free-spirited beauty named Penny moves in next door. Leonard sees in Penny a whole new universe of possibilities... including love.
