Question
There is a particular episode on Roseanne when both Becky's appear on the same show at the same time. They do a little skit where Roseanne jokes about the new Becky not actually being the real Becky. I'm trying to figure out what exact episode that was... if it wasn't an episode, it may of just been a blooper maybe. Not exactly sure. Any info on that?

Someone already answered this in depth for me at Yahoo answers.  Here is the link:

Two Beckys

During the show's fifth season actress Lecy Goranson left to attend Vassar College. At first, her character Becky was merely absent from the show, explained in the story when she marries and moves away to live with her husband Mark. During the sixth season, however, the show's producers recast Becky with actress Sarah Chalke. This change is addressed in the show which becomes a running gag for the remainder of the series as both Goranson and Chalke continue to alternate in the role of Becky, depending on Goranson's availability. Examples of this gag include:

At the end of Chalke's first episode, the Conner family watches the television show Bewitched and several characters complain about the recasting of the show's main character Darrin Stevens, with Chalke asserting that she prefers the second actor to play Darrin.
In the season six episode "Suck Up or Shut Up," when Luke and Laura from General Hospital are with Roseanne in the diner, they are explaining all the mishaps they have had (as the result of being in a soap). Roseanne responds with "Well our daughter Becky was gone for a year and when she came back we barely recognized her!!"
When Goranson returns to the role in the eighth season premiere, Roseanne and Darlene ask Becky, "Where the hell have you been?" and comment that "it feels like you've been gone for three years." Becky responds, "Why does everyone keep saying that?"
The eighth season premiere concludes with Goranson and Chalke dancing as if they were each other's reflection in a black-and-white parody of the closing credits from the television series The Patty Duke Show, a series in which actress Patty Duke plays two identical cousins. The song to which the two Beckys dance, "Nearly Identical Beckys", is set to the tune of the theme music from The Patty Duke Show'. At the end of the segment, William Schallert, who plays Patty's father on the series, appears with Dan. This parody was excised from the eighth season DVD box set.
Beginning with the eighth season, the show's opening credits sequence, which displays morphing images of the main characters over the years, features images of both Goranson and Chalke in the role of Becky.
When Roseanne announces that the Conner family is planning a vacation to Walt Disney World, Becky (played that week by Chalke) tells Roseanne how excited she is to be going to Disney World. Roseanne responds, "Aren't you glad you were here this week?"
In an episode that pretends to glimpse into the future, John Goodman portrays an adult version of D.J. who has suffered a mental breakdown. He repeatedly mutters "They say she's the same, but she isn't the same." At the end of the episode, a montage sequence of the two actresses playing Becky reveals the meaning of D.J.'s mantra.
Because cast and crew believed that the eighth season of Roseanne would be its last, Goranson had signed back on only for that season. When the show was renewed for a ninth season, Chalke replaced Goranson full-time.

Thanks!
