SEVEN
Seven appeared in season seven (hence his name), in what appeared to be an attempt to appeal to a more mainstream audience. He has nothing to do with Peggy's pregnancy in early season six. This first recurring character apart from the usual six principals (four Bundys and their two neighbors) was played by Shane Sweet. Peggy's relatives Zemus and Ida Mae come to visit the Bundys in 0701 and just leave Seven there. Zemus' expanation for Seven's name is that they have one, two, three, four, five, seven children.
