My wife and I wrote the following for a poetry contest by Science News. It didn't win, so I posted it on my web page.

If computers that you build are quantum,
Then spies of all factions will want 'em.
Our codes will all fail,
And they'll read our email,
Till we've crypto that's quantum, and daunt 'em.

Jennifer and Peter Shor

When he introduced me at the 1998 International Congress of Mathematicians, Prof. Volker Strassen recited my limerick, and added a reply:

To read our E-mail, how mean
of the spies and their quantum machine;
Be comforted though,
they do not yet know
how to factorize twelve or fifteen.
