People often say that the term "meathead" comes from the classic 1970s television situation comedy "All In The Family," in which main character Archie Bunker (Carroll O'Connor) used the nickname to address his son-in-law, Michael Stivic (Rob Reiner), beginning with the premiere episode ("Meet the Bunkers") on January 12, 1971. However, the term first appeared in print in 1863.
