And they made a mistake there: the prizes were a lot of folderols and doodads like poetry books and illustrated Testaments, instead of something a real live kid would want to work for, like real cash or a speedometer for his motor cycle.
Where it comes from
Originally a nonsense refrain in songs, since circa 1701, as "fal, al, deral!", and 1820, used to make the song longer without adding more meaningful content (see non-lexical vocables in music). Compare falleri, fallera, extended as falleralla or fallerallera, in Swedish and German songs.
