When you’re 22-months old, the two greatest things in the world are trains (”choo choo”) and merry-go-rounds (”why-oh-why”). If you say “choo choo” and “why-oh-why” over and over again, it sounds a little like the lyrics to a Kajagoogoo song. And then that song becomes another one of the greatest things in the world.
