Mike thinks that the husband should be the "aggressive" member of a married couple. Gloria claims she doesn't care, but Mike thinks he can read through the lines of her indifference. As a result, Mike and Gloria's romantic evening degenerates into a high-decibel argument. Focusing almost exclusively on series regulars Rob Reiner and Sally Struthers, this episode was written by Don Nicholl. "Mike and Gloria Mix It Up" first aired on January 5, 1974. ~ Hal Erickson, Rovi
