History
Sherri and Terri were both impregnated by Nelson 7/8 years in the future. They gave birth shortly after the school prom. Later, at a party in Homer's underwater house, the twins had each given birth to a set of twins, making four children.

Nelson abandoned the children, however another 7 years into the future he was seen with a young son, Nelson Muntz, Jr., who may have been one of the four twins.
