“Never forget your roots” usually means not to forget one’s upbringing and ancestral roots, but a joke applies the saying to root vegetables. This was posted on Reddit—Cleanjokes on November 30, 2022:
     
“Potatoes, carrots, parsnips, turnips, beets, yams…. I’ll never forget my roots.”
   
     
Wikipedia: Root vegetable
Root vegetables are underground plant parts eaten by humans as food. Although botany distinguishes true roots (such as taproots and tuberous roots) from non-roots (such as bulbs, corms, rhizomes, and tubers, although some contain both hypocotyl and taproot tissue), the term “root vegetable” is applied to all these types in agricultural and culinary usage (see terminology of vegetables).
