MKF diease comes in the form of a small, redheaded girl around 4"11. Side affects include being unbelievably annoying, singing at random times, and being allergic to the opposite sex. To avoid this *fatal* disease, place RoseMary above your door, and continuously play songs from the Broadway Classic, "Once Upon A Mattress"
Kasey: OH DEAR! I THINK YOU CAUGHT MKF disease!!"
Mary Kate: OH NO! NOW I'LL NEVER GET A BOYFRIEND!
