From the New Haven Independent, concerning my recent Trebekistan-related appearance at Yale:

Again, there was no charge (unless you count parking tickets!)  Bob Harris was worth it!

It seems from the context that the writer was actually trying to say that hearing my talk was worth (a) the trip, (b) the bother, (c) the cost of a parking ticket he or she must have gotten, or (d) some object of value, possibly forgotten in the giddy excitement of a trip, a bother, and a parking ticket.

I almost wish it was actually meant as an insult.  (Maybe it is!)  Free — and worth it!  That’s outstanding.
