Double Column

I was reading through some older stuff that Cecil wrote and came across two versions of the same column:

If the groundhog sees its shadow Feb.2, why does that mean six more weeks of winter?

and

If groundhog sees shadow, why MORE winter?

Note that the titles are different; not only that, the beginning and end of the columns differ slightly also.

Which is the original, and why are there two copies of the same?
