this is what it sounds like when pigs fly

Have I missed something? Did The WHO recently get back together and start writing songs about flying pigs? I keep hearing it (or about it) over and over and over again. This is like the comeback of the century, right? Whew. So much hubbub. I need s' wine. A bottle-a red...a bottle-a white...

(For real, someone please make it go away.)
