Meathead - Archie Bunker (Carroll O'Connor) called his unemployed son-in-law Mike Stivic (Rob Reiner) a "meathead" on a regular basis on the sitcom ALL IN THE FAMILY/CBS/1971-83. Mike stayed with his in-laws while going to college. The cramped quarters and the volatile tempers of both Mike and Archie often put them at odds with each other resulting in Archie calling Mike a "Meathead" which was once explained to mean "dead from the neck up." Archie once commented to his wife (Jean Stapleton) "We lost a daughter, Edith, but we gained a meathead." Archie also called Meathead a "Knucklehead!" During the 1982-83 season Mike Stivic divorced his wife, and ran off to a commune with a flower child, thus fulfilling Archie's opinion of him. In high school Archie was also called Meathead.

TRIVIA NOTE: The son-in-law counterpart on the British sitcom TILL DEATH US DO PART/BBC/1966-75 that inspired ALL IN THE FAMILY was referred to as a "git."  See also - "Shoebootie"
