Not sure who the surfer dude is, but the two women are Emily and Lisa DiNapoli. Emily was played by Julia Condra and she married the equally bland Greg Hughes. Lisa was played by Tawny Kitaen in this scene. I think Tea Leoni also played the role for a bit. They had another sister, Celeste, played by Signy Coleman. And, yes, Greg was horrible. It was around this time that I tuned out of SB. Paul Johannson, who played Greg, later appeared on One Tree Hill for many seasons.
