I did my PhD thesis on PSR J1023+0038, a millisecond pulsar that is at a fascinating point in its evolution. (In fact there have been developments since the thesis was submitted; more about that later.) But during a moment of procrastination, I got involved with a new and fascinating system. The name, unedifying as usual, is PSR J0337+17, and it is unique in that the pulsar has not just one white dwarf companion but two.
