Simon Helberg, who plays Howard, explained, "I don't know. We've been out there handing out those fliers for years. I guess now it's on in syndication so much that you can't avoid seeing it. Anything I'm on, I search out and watch. (Laughs) I have the DVR set and then just fast-forward through everyone else's scenes.
Meanwhile, Jim Parsons, who plays Sheldon, admitted that he rarely even watches the show, "I normally change the channel if I see it but, recently, I watched it until the end and it was really fun. It was long enough ago that things had changed. (Turning to Bialik) It was the one where you wanted sex," he added.
