Olga Nielsen is a fantastic bowler and identical twin sister of Sonya Nielsen. Her boyfriend, Lars Lindquist, mistakenly sleeps with her sister Sonya and Sonya did not tell him he didn't have the right sister. He was later found dead in his Volvo dealership, and he requested an authentic Viking funeral. The funeral failed several times, however, because the coast guard kept putting out the fire when they set fire to him and his ship, and so the funeral had to be rescheduled for the day they were supposed to compete with Dorothy and Blanche, making Rose and Sophia their competitors. Olga and her sister Sonya are both mentioned in the Season 1 episode of The Golden Girls titled "The Competition" (ep,#7).
