In any case, myths about the habits of the French do not properly count as education. Nor can I think of any bawdy song that actually imparts information that might be useful to the young. However, the following limerick does at least embody some conventional wisdom:

There was once a young lady named Sue
Who preferred a stiff drink to a screw,
    But one leads to the other,
    And now she's a mother --
Let that be a lesson to you!
