Irish Sergeant,

I'd agree that children's rhymes are amongst the best examples of the oral tradition still in existance. (apart from jokes, maybe)

Lots of people have catalogued these.

Not sure what you mean regarding your 'Comet' commercial. Is it something that was chanted years ago, and is still today?

As a general rule, I wouldn't think that parodies of commercials can become 'traditional' because the 'joke' is likely to be tranisitory and soon forgotten.
