    Stopped watching TBBT during season 7 when it turned into a Friends remake, and its now just a cliche of liberal ideals. First 4 seasons were the best.

    Great except for everything and I mean everything in the opening theme song is incorrect ...SCIENTIFICALLY. The universe started out between 32 deg F and 212 deg F (water in a liquid state)..and the big bang will occur at the END of the universe. Everything man says about the world is 100% opposite the truth....MORE>>>>

    Except that there are a LOT more lyrics than that to the entire theme song.

    Our whole universe was in a hot, dense state
    Then nearly fourteen billion years ago expansion started...wait
    The earth began to cool, the autotrophs began to drool
    Neanderthals developed tools
    We built a wall (we built the pyramids)
    Math, science, history, unraveling the mysteries
    That all started with the big bang

    Since the dawn of man is really not that long
    As every galaxy was formed in less time than it takes to sing this song
    A fraction of a second and the elements were made
    The bipeds stood up straight, the dinosaurs all met their fate
    They tried to leap but they were late
    And they all died (they froze their asses off)
    The oceans and Pangea, see ya wouldn't wanna be ya
    Set in motion by the same big bang
    It all started with the big bang

    It's expanding ever outward but one day
    It will cause the stars to go the other way
    Collapsing ever inward, we won't be here, it won't be hurt
    Our best and brightest figure that it'll make an even bigger bang

    Australopithecus would really have been sick of us
    Debating how we're here, they're catching deer (we're catching viruses)
    Religion or astronomy (Descartes or Deuteronomy)
    It all started with the big bang

    Music and mythology, Einstein and astrology
    It all started with the big bang
