What your grade school music teacher never told you.
...is that it's important to pay attention to those goofy songs she teaches you, because one day, some twenty years later, you will find yourself driving down the road, desperately trying to serenade your crying baby with "Magalina Hagalina" and "On Top of Spaghetti" in order to stave off his sorrow at having dropped his nuk on the floor in Elder Beerman's. And if you cannot recall a verse, simply singing, "Third verse, same as the first," will not cut it, and then he and you and Mrs. Curly will know that you are a big fat failure when it comes to children's songs and comfort of any kind. And then what will you do???
