Big Bang Theory Pilot Revisited: 15 Memorable Moments (Including a Few In-Hindsight Continuity Errors)

In honor of The Big Bang Theory‘s 15th anniversary, TVLine is revisiting the episode that started it all. No, not the unaired, 2006 pilot that only exists in the deepest, darkest corners of the Internet, but the reshot pilot that became the actual series premiere, which aired on Monday, Sept. 24, 2007.

Our rewatch left us with more questions than answers. Among them: What ever happened to Penny’s screenplay? Was Sheldon getting pantsed a blessing? And where would Howard have wound up without Bernadette?

All of the above barely scratch the surface. We’ve also made note of several in-hindsight continuity gaffes (which serve to underscore just how much the show and the central gang has evolved since the pre-Amy Farrah Fowler era). And while much had changed after Penny  moved into Apt. 4B, there was at least one constant for the duration of Big Bang‘s 12-season run. (Hint: It involves a certain seating arrangement.)

All 279 episodes of The Big Bang Theory are available to stream on HBO Max (sign up here). Keep scrolling for a shot-by-shot stroll down memory lane, then hit the comments with your reactions.
