An entertaining inscription by the editor, Harry M. Orlinsky, in honor of "Saint Valentines day"

I recently came across a copy of Introduction to the Tiberian Masorah by Israel Yeivin, with an entertaining inscription by the editor, Harry M. Orlinsky, which reads:
לכבוד הרב משה בן יצחק הלוי ערב יום ולנטין הקדוש תשמ"א
"In honor of Rabbi Moshe ben Yitzchak Halevi, the eve of the say of Saint Valentine"
