Background: The informant is a woman in her late fifties who grew up in downstate New York in Queens and on Long Island before moving to upstate New York for college. In her mid 20s, she moved out to Southern California and she had lived there ever since. She comes from a large family of Catholic Irish-Americans.
“If you don’t clean out your ears or bellybutton, you’ll grow potatoes there.”
Context: Typically, this warning is told to children as a way to incentivize them into proper hygiene. As the informant explained it, there was an association between the dirt that gathered when someone didn’t clean their body and the dirt that potatoes grow in. The saying came directly from her grandmother, who emigrated from Ireland to New York as a young adult. However, the saying seemed to backfire for the informant—she admits that she never wanted to clean her ears or bellybutton after being told this hyperbole, just so she could see if potatoes actually grew.
Thoughts: The informant happens to be my mother, so I also grew up with this saying. Similar to her, I found the lie to be more interesting than scary, and as a young child I also avoided cleaning my bellybutton just to see what would happen. It’s interesting how these types of rumors can actually backfire on gullible children, instead encouraging them to do the opposite of what they’re told. I wonder if my great-grandmother knew that when she used the phrase, and only repeated it to her children and her children’s children because she found it amusing. This phrase also reminds me of another popular schoolyard rumor, where supposedly if you swallow a watermelon seed it will grow inside of you. The Irish Potato warning seems to be somewhat less widespread in the United States. None of my friends can recall a similar warning, and the only other place I’ve encountered it being used it in Frank McCourt’s book Angela’s Ashes, a memoir about Irish-American immigrants.
