So expound it to me, Dick. No good just being assertive; let's hear your interpretation, and your assertion of what the 'point' is, based on the accepted versions of the legend:-

Canute demonstrates to his flattering courtiers that he has no control over the elements (the incoming tide)

Your use of the term re Jim & me suggests that you accept the vulgar analogy of one who really thought that he could halt the tide; when that was not the point he was making at all.

Over to you...
