Plot summary
Greg's date Sandra (Cindi Crosby) cancels when her cousin Linda (Kathie Gibboney) visits from out of town. Wanting to salvage the date, Greg plans a double date. When no one wants to pair up with Linda, he turns to Peter, passing him off as a "friend" in his high school class named "Phil Packer". Linda and Sandra discover Greg's ruse but do not let on, and hatch a plan of revenge at a pizza parlor. In the subplot, Carol and Mike – on Jan's and Marcia's recommendations for great pizza – are entertaining a conservative client Juan Calderon and his wife Maria there. Sandra and Linda's revenge nearly jeopardizes Mike's deal.
