It looks like the pattern is quickly being established on "Rob" (Thu., 8:30 p.m. EST on CBS). To the show's credit, the ethnic jokes took a back-seat to setting up the fun of Rob being trapped between all these warring factions in his new family. This week, it was about him robbing Maggie's parents of the chance at her dream wedding.Maggie admitted that she had dreamed of her wedding day -- to Marky Mark no less -- but as the episode progressed, it became clear that it was more her mother Rosa's dream to throw her daughter this fabulous wedding.
