It's Make Your Own Dick Joke Day at FTT

A Japanese medical journal has reported a rare case of phantom erectile penis. The patient underwent sexual-reassignment surgery (he became a she) and, in the days following, began to experience a bizarre sensation: His (or her) penis was still there! It was erect! And there was nothing he (or she!) could do about it! In the end, the doctors decided to pursue a second surgery, in which all the remaining genital nerve fibers were removed; after six torturous months, the phantom erection disappeared. A flaccid penis never felt so good. - Very Short List

I'd comment on this, but my brain just exploded.
