I don't want to trivialize this excellent thread, but when we were singing with migrant farm-working families in the New York State orchards, some of the kids sang:

    I'm a little piece of tin,
    Nobody knows the shape I'm in.
    Got four wheels and a runnin' board.
    I'm a Ford, Lord, I'm a Ford!
         Honk, honk, rattle, rattle, rattle, crash, beep, beep.
         Honk, honk, rattle, rattle, rattle, crash, beep, beep.
         Honk, honk, rattle, rattle, rattle, crash, beep, beep.
         Honk, honk, rattle, rattle, rattle, crash, beep, beep.


Then one of the mothers sang (same tune, slightly blues-ified):

    I'm a little nut so brown
    Lyin' on the cold, cold ground.
    Everybody steps on me;
    That is why I'm cracked, you see.
         Honk, honk, rattle, rattle, rattle, crash, beep, beep.
         Honk, honk, rattle, rattle, rattle, crash, beep, beep.
         Honk, honk, rattle, rattle, rattle, crash, beep, beep.
         Honk, honk, rattle, rattle, rattle, crash, beep, beep.
