Post a song you know all the lyrics to by heart

Post a song you can recite the lyrics to effortlessly. You know 'em by heart, and in the case of some people, you wish you didn't. You can only post ONE song.

"Ebay" by Weird Al Yankovic.

I first heard it in third grade and I learned all the lyrics in a day and a half. Even after all those years, I still can recite all the lyrics without fail.
