That must be a model of one of those "alternative c-sections" I keep hearing about. You know, where you get to literally shit out the baby through an auxillary anus grafted onto your abdomen?
I'm guessing somebody put that velcro-attached wang on there in order to set up a lame pun. Like, you know, "Gives new meanig to the term "shit dick", you know? HAHAHAHAHA! You know, like if some diarrhea dribbles out? Ha! I slay me! Guys?"
