Twitter asks "Last book that made you cry" and someone replies "University Physics with Modern Physics 14th Edition by Hugh D. Young, Roger A. Freedman" to which co-author Freedman himself responds "No doubt tears of joy."
Let's be real—the only thing flowing more freely than those tears was probably the crushing despair of trying to understand angular momentum at 3 AM before the final. The author showing up to essentially say "you're welcome for the emotional damage" is peak academic schadenfreude.
