The Back Story was the 15th episode of Season 4 of Roseanne, also the 87th overall series episode. Written by Bob Myer, the episode was directed by Andrew D. Weyman. It originally aired on ABC-TV on February 4, 1992.
Bev arrives to help when Roseanne throws her back out, in time for DJ's 10th birthday. Dan's thrilled with a rare opportunity to spoil his kids when he secretly buys DJ a Super Nintendo video game console and strikes a car-buying deal with Becky, but is upset when Bev swoops in and beats him to the punch.
During the end scene, Roseanne is playing what sounds like Super Mario World.
