Like Marrying Like: Petri and Stromberg

Ms. Petri usually does well in her humor columns, but Saturday's was very good.  Then I see this notice in the NYTimes, explaining the marriage.

In the old days Mr. Stromberg would have married his secretary, who would have been his better half.  Now he marries a columnist, who's still his better half.  I can't complain, since the marriage produces the column, but it's assortative mating.  Unfortunately it reduces social mobility. 

But read Petri's piece.
