Lies was the 22nd episode of Season 4 of Roseanne, also the 93rd overall series episode. Written by Sid Youngers and Joel Madison from an original story by Jeff Abugov, the episode was directed by Andrew D. Weyman. It originally aired on ABC-TV on March 24, 1992.
Roseanne frets when she must take a lie detector test at work. Darlene bypasses Roseanne (going to Dan instead) for advice on dealing with boyfriend David.
Roseanne considers trying to cheat a lie-detector test at Rodbell's because she's been stealing food- but it turns out the investigator is more interested in learning about Leon's background than about hers. Ultimately, she doesn't lose her job. Meanwhile, Darlene asks Dan and Becky for advice about her relationship with David (Johnny Galecki) who is clearly attracted to her; she is also attracted to him, but not sure if a romance will interfere with the friendship they already have. Roseanne gets upset because Darlene didn't go to her (although David did) and repeatedly takes out her frustration at this on Dan. At the end of the episode, Darlene and David have their first kiss on the basketball court.
