Synopsis by Andrea LeVasseur
Dan and Roseanne get an invitation to their 15th high school class reunion. While looking over some old photographs to bring for the yearbook, Roseanne finds out that Dan had a fling with another girl a long time ago. It was only a one-night stand, but it was with Roseanne's high-school nemesis. The girl turns out to be Phyllis Zimmer, who is played by Vicki Lawrence in an episode during season six.
