Guess what I've got? My initial thoughts were female genitalia or swine flu. I'm very happy it wasn't the second one.
Inspired by Glenda, the Good Witch of the North (or in my case East): A friend once told me a great way to get a song out of your head. I've tried it and it works. Sing "row row row your boat backwards." Dream a but is life Merrily, merrily, merrily Stream the down gently Your boat row, row, row
Uhhhmm... ITs cause brother Micheal does indeed read from right to left EDIT: ANd of course, from botom to top As for the original poster, I was also gonna go with Herpes.
Pfffft, like you just saying the song would actually get it stuck in my head. How gullible do you think I having the times of our liiiiiives, DAMN IT!
