Re-runs are inevitable- that's for sure. This 2 part finale ended so beautifully that I had tears in my eyes. Nobody can imagine a sitcom endes with such powerful emotional impact. Thank you once again Big Bang. Thank you for being part of my life.
The "Previously on the Big Bang Theory" segment includes clips from throughout the series showing important events or long-running jokes instead of the usual format of including relevant and more recent previous events that relate to the current episode. It begins with Penny meeting Leonard and Sheldon in the pilot. Also included are the weddings of the main characters. Funny elements include the habit of Sheldon to knock three times and the singing of the song Soft Kitty.
The DNA model falls apart as soon as Leonard touches it. In The Spock Resonance (2015) Sheldon moves the DNA model out of the way to get to the wall safe without any concern of it falling apart and it stays intact.
