This classic black t-shirt features a humorous definition of "Ph.D." The design playfully describes a Ph.D. holder as someone who does "precision guesswork based on unreliable data provided by those of questionable knowledge." A fun alternative definition: wizard, magician. Made from a soft-feel fabric, this tee is perfect for academics, graduates, or anyone with a witty sense of humor. It’s an ideal conversation starter and a comfortable everyday wear item. Show off your smarts with this clever and unique t-shirt.
