You can still see the scene in the pilot’s original cut on Max, but it’s been pulled from syndication. Creator Chuck Lorre has since said, "The scene was so wrong."
Lorre said, "In my mind, the show truly began with those awkward hellos between Penny [Kaley Cuoco], Sheldon, and Leonard when she's unpacking boxes in her apartment."
Parsons didn't have a problem with the scene in the moment, but gets Lorre's decision. "Looking back, it was out of place, but there was no way for the producers to know," he said.
