// Big Bang Theory airs its 200th episode on Thursday night – but as it turns out, there’s still a lot we don’t know about the characters from the beloved CBS sitcom.

In a new video for, the stars of the series get candid during a red carpet quiz while celebrating the 200th episode party at Vibiana in Los Angeles.

A few highlights: Johnny Galecki, 40, is “least nervous and most comfortable half-naked” when playing Leonard, and Jim Parsons, 42, wishes his character Sheldon would have a “secret one-night stand” with Penny (Kaley Cuoco) because the “after-coitus conversation would be so enjoyable to play.”

Meanwhile, Cuoco, 30, chose 93-year-old comic book writer Stan Lee as Penny’s dream hook-up: “He’s hot, you guys!”

The stars also revealed which Friends character they would most want to make a cameo (it’s Jennifer Aniston for Cuoco: “She’s my secret best friend – in my head”), and all the wacky nicknames they have for each other (Cuoco and Galecki, “from day one,” have inexplicably called each other “mooks”).

As for which actor is most like his or her character, that was an easy guess – it’s real-life scientist Mayim Bialik because she “most literally understands what the hell we’re talking about,” Parsons said.

Bialik, 40, agreed: “Probably me, not just because I’m a scientist, but I’m kind of fastidious and nerdy and geeky.”

But even after nine and a half years filming the hit series together, there’s still one thing the tight-knit cast can’t do: spell costar Kunal Nayyar‘s character’s last name, “Koothrappali.” (Hey, we don’t blame them.)

The Big Bang Theory airs Thursdays (8 p.m. ET) on CBS.
