From his mailbag column today:

Q: I have watched “Ferris Bueller’s Day Off” at least 200 times. Recently, I asked this question — I have no idea what the answer is — and now find the movie completely unwatchable: WHAT HAPPENED WHEN ABE FROMAN SHOWED UP AT THE RESTAURANT? Are we to believe Abe never showed up for his reservation, followed by Ferris and his crew getting tossed? It makes no sense. — Scott Marx, New York

SG: Wait a second … that’s what made “Ferris” unwatchable for you after all these years? You weren’t fazed by Ferris inexplicably jumping on a parade float and belting out “Twist and Shout” and “Danke Schoen” to the entire city of Chicago? Or Cameron destroying his father’s million-dollar car for no real reason, then his friends assuring him that he did the right thing? Or the guy who played the Principal getting arrested for child porn charges in real life? You’re going with Abe Froman? Really?

The Abe Froman question is the great unsolved mystery of that movie.  They sat down and had a whole lunch and he never showed?  And Ferris had no plan in case he did show?  It’s a problem.

Of course, I also think Sloan and Cameron get married after the movie ends, but that’s just me.
