    "Deja Vu"

    Loved this more than a lot of the others this season. Sheldon's definition of Deja Vu was something I had never heard before and will take some time to research and process, but I loved that they did THEIR research and put it in. The moment in the car with Sheldon & Leonard when they are entering Alhambra was hysterical, not only because it was well-written, but also because of Jim Parsons' impeccable timing. Many other nice moments and funny dialogue (like Bernadette and Howard discovering the Loch Ness monster headline about Raj). Nice work, guys!

    Very good episode!

    The end game... and now the end of tbbt. Sheldon talking about hulk... and Leonard trying to not be a Leonard. Very good!

    Thank God is the last season

    0 jokes, annoying recorded laughs, The act are poor the script even more idiotic. Just realese the last episode. This is not Big Bang Theory is Big Boring Tv

    You Can't Always Get What You Want......Can You?

    Leonard is as whiny as ever. He can't make decisions. Raj becomes a media nut case when a slip of the tongue propels him into the tabloids. There's not much here to be quite honest.

    Where are the laughs??

    With only a few episodes left you would think the show would be funny. This episode was horribly boring and nothing was funny about it. I miss the first few season when you had a good show and you genuinely laughed. So disappointed it's ending but maybe that's a good thing?

    • Trivia
      The new Avengers movie the gang is going to see is Avengers: Endgame (2019), which had been released three days before this episode's broadcast. Bernadette says that she wants to see the movie in 3D because she wants to feel close enough to lick Thor's abs; she will be disappointed, because in the movie, Thor sported a large beer-belly.
    • Goofs
      Leonard, sitting on a stair, says, "I've always been a people pleaser. Is that so bad? It's gotten me this far." Amy replies, "What, almost up four flights of stairs?" However, they live on the fourth floor, which is only three flights of stairs up from the lobby.
    • Quotes

      [last lines]

      Sheldon Cooper: Have you ever wondered what the Hulk would be like if he were made of sherbet?

      Leonard Hofstadter: I give up.

      Sheldon Cooper: Delicious.

      The Adventures of Ebb and Flow

      one-page synopsis

      Jeffcoat (Jeff) Ebb: Overly polite, easygoing, soft-spoken. Given a choice - and he is always given one - Jeff's preference is to back away from trouble.

      Jackson (Jack) Flow: A hard charging, hot-tempered, fight first, fight later kind of guy. Jack's first instinct is to put his head down and go!

      Together they are: Ebb and Flow, two men you can always count on to get into a tough situation, and then withdraw.
