A nursery rhyme was a popular poem or song that is usually intended to be recited, read or sung to children. Nursery rhymes are some of the most popular folk songs in both Europe and North America, although they are actually quite common and popular all over the world. The supervillain Cyrus Gold, is called Solomon Grundy, which is also the name of a popular nursery rhyme. Marvin White often recited nursery rhymes. He once recited rub-a-dub-dub when he said: "Rub-a-dub-dub, three men in a tub." He said this because he had fashioned a mushroom into a boat.
