Mine is the last one,

The Stockholm Syndrome .

From series 1-12

Hey Everyone, I am new here! And I love TBBT and to say the truth TBBT is responsible 20% for making me loveeeee physics and mathematics....

In the season 3 episode 22 Sheldon and Leonard are preparing roommate agreement. Sheldon puts a point in the agreement that if in future they invent time travel then they will meet their past selves exactly at this same place where they are composing the agreement. And meet 5 seconds later as soon as they have finished composing this point in the agreement. Sheldon, while sitting in his lawn chair and immediately after putting that point on paper, starts looking all around the room hoping to find their future selves appear. To Sheldon's disappointment that didn't happen. How can, in case according to Sheldon they invent it, their future selves know the exact time? Sheldon is writing that point in the agreement to appear immediately after 5 seconds he writes that point. I believe that he has to write the exact time in the agreement so that their future selves can know when to appear. Are we to assume that he wrote the exact time, ie the time of writing that point, on that paper?

This particular part of the song - "began to drool. Neanderthals developed tools". I keep mishearing every time I listen to it on TV. To me it always sounds like "beganatoosmi".

Anyone noticed that, over the seasons, Sheldon gets better at letting people in his spot, and eventually will let people sit in his spot as long as he doesn’t want to sit there.

that's it. Bazinga!!
