What should Jeff Holmes ask Alex and me?

Rumor has it that there will be a special edition of Conversations with Tyler, to commemorate the pending 20th year anniversary of Marginal Revolution (yes, we have posted multiple times each day, without exception).

We will be recording, of course, in Chennai.  So what should Jeff ask Alex and me?  If you don’t already know, Jeff from the inception has been the producer of CWT.
