I remember as a kid watching I Love Lucy reruns and in one episode Lucy & Ethel end up “ride-sharing” with a stranger (played by Elsa Lanchester) down to Florida. They stop for a snack and the only thing available are Watercress sandwiches. I had never heard of that before but knew by Lucy’s smooshed face that it had to taste atrocious. Now that I am semi-grownup, I have to say I think she was wrong in her assessment.
