Are Sheldon Cooper and Amy Farrah Fowler ever going to get past second base on "The Big Bang Theory"? Not if Mayim Bialik, who plays the nerdy neurobiologist on the CBS hit, has any say.
"I kind of like us the way we are," she told TODAY.com.
"Sheldon made a comment that he could picture the two of them having coitus (and) honestly, I was surprised that the producers were ready to have his character say that," shared the former "Blossom" star.
"I think it's really sweet that we depict an as-yet nonsexual romantic intimate relationship that is very sweet. But anything can happen on our show."
That includes some kinky spanking, the unforgettable moment that fans can enjoy (or cringe about) again on Thursday's rebroadcast of "The Fish Guts Displacement."
Originally, viewers weren't intended to actually see Sheldon deliver the corporal punishment to his "very bad girl" girlfriend.
"The naughty was (originally) supposed to be off-camera," Jim Parsons revealed at PaleyFest last month, adding: "It was one of the hardest things I've ever had to do -- because I found it tremendously amusing."
But Bialik paid the price for the her co-star's repeated attempts "to get the sound we wanted": "There was some redness," she admitted.
"One thing I like about Amy is that she's very honest almost to a fault" -- except when she's tricking Sheldon, Bialik told us. "She's not afraid to bend the rules in terms of what's expected of her, or what people think she should act like, dress like, be like (or) have a relationship like."
And like her brainy character, Bialik wants to encourage girls to pursue the sciences. The actress has even partnered with DeVry University to inspire young women to pursue their goals.
Unfortunately, Bialik didn't share any screen time with legendary comedian Bob Newhart, who is guesting on the show May 2.
"I'm not in (the) episode sadly, so I did not get to meet him," said the chagrined actress. "It's really a bummer. I've been a huge 'Newhart' fan and spent many -- I don't know if they were lonely teenage years, but many appropriate teenage years watching ''Newhart' late at night."
When we asked Bialik what other series she'd like to guest on herself, she confessed, "I don't watch television. I've heard of shows. I was a huge fan of 'Northern Exposure' 20 years ago. I actually was seated next to (its star) Rob Morrow at this Alzheimer's benefit the other night and I was geeking out in my head the whole time. I've heard that 'Downton Abbey' is a good show and I sometimes look good in period pieces, so that might be fun."
(Maybe Lady Edith can interview famous scientist Marie Curie for her newspaper column?)
As to where "Big Bang" is headed, Bialik is completely in the dark.
"We know nothing" about the upcoming sixth-season finale, she told us. "(The writers) sort of go where their passion takes them!"
