This awesome spoof shirt has an iconic style that copies the famous album cover from Pink Floyd, The Dark Side of the Moon.

Here the familiar triangle rainbow prism design includes an archive photo of Dr. Sigmund Freud inside, and the image is titled Pink Freud using all capital letters above the image. This alone is pretty funny and easy to read from a distance.

But the Dr. Freud spoof t-shirt image has a smaller subtitle underneath which reads: "The Dark Side of Your Mom" (also using all caps). Sigmund Freud is, of course, noted for his work on the Oedipus complex theory, which describes love/hate relationships between children and their opposite/same sex parents.
