I just checked your profile and I heard the correct version before you were born too. What is it with kids these days? Some television show comes and changes the words to a silly rhyme and everyone born after the fact forgets the way it was originally.
There's a difference between a rhyme and an approximate rhyme, by the way. I remember, back in the day, when all silly little rhymes actually rhymed.
Not that any of this has any bearing on actual life, of course. It's a silly thing to argue about.
