The Big Bang Theory star managed to carve out some time from his busy schedule to reprise his role as Darlene Conner's (Sara Gilbert) husband, David Healy, and according to Entertainment Tonight, he's already filmed his first episode! Even though he'll only appear in one out of the eight episodes, we're happy to have Galecki back. As we await his return, take a walk down memory lane and look back at Galecki in the original Roseanne.
