It reminds me of the story of the prisoner being examined by the psychiatrist. The latter shows the prisoner a series of abstract paintings, asking him what he sees. In each case, the prisoner associates the painting with various naughty bits of the human anatomy, and lewd acts performed with said bits.
At the end of the process, the psychiatrist tells the prisoner that he has a dirty mind. The prisoner replies, defensively—"Well, you're the one with the filthy pictures." :rolleyes:
