#### Abstract

Thanks to Robert Fulghum for providing a title to parody. In order to honor Doron on his 60th birthday, I will discuss a mathematical problem that I am currently working on, deliberately highlighting the useful advice that Doron gave me during my years as his postdoc, and via his famous Opinions page.

The mathematical content of the talk is joint work with Hua Wang. The Wiener index of a graph G=(V,E), which is the sum of minimal distances between every pair of vertices in V, was introduced by H. Wiener in 1947. We consider the problem of identifying trees of maximal Wiener index among all trees that possess a given degree sequence.
