A listener remembers her mother used to say, “Your Monday is longer than your Tuesday.” This phrase offered a subtle way to notify someone that her slip was showing. Other expressions convey that warning as well, including “Monday comes before Sunday” and “Saturday is longer than Sunday.” Also, if someone whispers “Mrs. White is out of jail,” it’s time to check to see if your slip is showing. Ditto if you’re told you have “a Ph.D.,” but you’ve never earned that degree. In this case “Ph.D” stands for “Petticoat Hanging Down.” This is part of a complete episode.
