Sara Gilbert and Roseanne Barr Share Secrets From 'Roseanne' Set

The two also reveal a gross prank George Clooney once pulled.

— -- "Roseanne" reunion!

"I was most like Darlene [Gilbert's character]," Barr said when asked which of her TV kids she felt most similar to. "I was kind of a rebel, and, you know, I had periods of depression and stuff like that, and I just thought that was a cool and very accurate way that a lot of girls are, especially intelligent, thinking, sensitive girls in their teens, so it was important to me to have that element in the show."

Barr, 61, had a moment with Gilbert, too, and said the actress-turned-talk show host really brought Darlene "to life" on screen.

Gilbert, 39, also had nothing but great things to say about working with Barr.

"Julie [Chen, her co-host] was saying, 'The pictures are so sweet,' and I was thinking, 'Well, it's because that chemistry was there,' Like, we were really a family. Without each other, there would be no show," Gilbert said.

"Every day, it was fun," Barr said.

"We used to have a few cocktails after we wrapped," Barr said. "Just the adults. George took a picture of his wiener. I don't know. What's the better word? ... He had these Groucho glasses and he put the Groucho glasses [on], so the wiener was the nose ... and he put that on the fridge for the next day when we came in."

The second day, the picture disappeared and hasn't resurfaced.
