As you can see from these X-rays, Miss... I mean Mr. Wirthling, you have begun what we call a spontanious gender transformation.
Is it fatal doc?
That all depends, little lady. How hard would it be for you to give up being ass-bumped by pink donkeys. You see, that is the cause.
Curses! If only I could have given up butt-snorkling gabe instead! But I can't turn my back on my donkey love!
Oh, it appears that turning your back on that donkey is all you really care to do. I'm afraid he will ride you into the ground within the next week. Sorry.
