Sheldon’s Fashion Statement: The Big Bang Theory Fans pay very close attention to even the tiniest detail on this show, and this extends to Sheldon’s wardrobe, which has not changed pretty much since the first season.

I will say maybe. I think there’re certain shirts for certain days, or at least it that’s the way things used to be."

"I would not rule this out," says Molaro. "It is something that she really enjoyed. Her present career is going on really well, but I would not rule out anything."

The Rostenkowski/Wolowitz Baby: The show’s cast weighed in on the name and gender of Howard and Bernie's baby, but what of the producers? "I have thought about it," admits Molaro. "I have not made any decision but I know it feels right now."
