The first-ever Necessary & Sufficient recorded live-to-whatever-you-call-the-digital-equivalent-of-tape at N&SHQ in Brooklyn. Brian was a great guest, and I love his remark about how simple the topic would be, right at the start of what turned out to be a 45-minute conversation. Everything is more complicated than you think.

Brian is wonderful. Great job!!
The 4 home runs in a game does have the significance that on average each player gets about 4 at bats so it is thought of as hitting a homer at every opportunity.
