A Pee h.D.
Explanation: This joke is a pun on the academic title “Ph.D.” (Doctor of Philosophy), humorously replaced with “Pee h.D.” The word “pee” refers to urination, making it a funny twist on the idea of earning a degree at a urinal. The joke works through the clever play on words, turning a serious academic accomplishment into a lighthearted bathroom-related pun.
