VIDEO : Johnny Galecki To Return As David For 'Roseanne' Revival

Following months of speculation, The Big Bang Theory star Johnny Galecki is finally set to return as David for the upcoming ABC revival of Roseanne. The revival was first confirmed in the spring, but Galecki's involvement has been up in the air.
