The sixth season of Big Bang has 1 married couple (little Howard and little Bernadette), Penny is back with Leonard (the shorter guy with glasses), and tall, thin Sheldon is s-l-o-w-l-y getting into a relationship with fellow supergeek, Amy. Why, they sit on the bed together and he gives her a stiff hug this year! Raj's sister, Priya, is gone. (Who knows? she may be back next season). Stuart, the cute little Comic Book Store owner gets a little more air time this season, he's always good for some laughable retorts. Raj is seeking and seeking a girlfriend; he finally meets a quirky girl toward the end of the season (heavy emphasis on quirk- she makes Amy seem normal), but will he get her into a continuing relationship? we don't know, stay tuned for Season 7. Even though there are the same three couples all season, it doesn't get stale because the writers always throw new wrenches into the works: we meet the university's HR (personnel) director (the 1st black chartacer) and the boys all get into HR trouble, we catch a glimpse of Howard's mother ( whoa! ), and Sheldon gets a beautiful new Assistant. Will she break up any of the couples? Dunno yet, stay tuned for Season 7! This is one of the best TV series ever! always funny lines and little scenarios along with each show's plot line.
