Beans, Beans, The Musical Fruit

"Beans, Beans, The Musical Fruit" is a schoolyard saying and children's song about the capacity for beans to contribute to flatulence. The song is also variously known as "Beans, Beans, the Magical Fruit", "Beans, Beans, the Miracle Fruit", and "Beans, Beans, the Wonderful Fruit". One variation of the song (sometimes called the second verse) is titled "Beans, Beans, They're Good for Your Heart."

The basis of the song (and bean/fart humor in general) is the high amount of oligosaccharides present in beans. Bacteria in the large intestine digest these sugars, producing carbon dioxide and hydrogen. These gases are expelled from the body as flatulence.
