'The Big Bang Theory' actress Mayim Bialik receives 'Doogie Howser' royalty check for two cents

Before Mayim Bialik’s lasting success with “The Big Bang Theory,” she appeared as a guest star in the hit series “Doogie Howser, M.D.” opposite Neil Patrick Harris.

That was back in 1990. Fast forward to 2012, the now-41-year-old is still receiving royalty checks from her appearance: a whopping two cents.

“That’s right. GROSS $0.02. NET to me: $0.01,” she captioned in an Instagram post on Tuesday with an image of the check.

The medical comedy-drama aired from 1989 until 1993.

But Bialik is doing just fine these days. Despite being on vocal rest for a month after spraining her vocal cords, Season 11 of “The Big Bang Theory” is scheduled to return on September 25.

“If you want me to tell you what happens in the season opener of Season 11…I can’t, because I don’t know,” she told Fox News. “Your guess is as good as mine!”

She may not have any inside secrets, but she does have a few “opinions and ideas.”

“I could see this playing out several ways,” said Bialik. “But that’s not my job right now. My job is to wait through the summer to see what our writers decide!”
