Mistaken lyrics

[Zeismyhero]

Hey! Have you ever thought that you knew the words to a song, only to have a revelation much later that you knew the wrong words all along?

For example, the song "Hey Santa Claus" (which is also featured in National Lampoon's Christmas Vacation) has a chorus that I swore was:

"Pigs and bones!
Pigs and bones!
Pigs and bones and bones and bones!"

when I was a little kid. I know it's pretty stupid, but kinda funny now.

Of course, even now that I know the error of my ways, I still have to sing it that way sometimes, but anyway...

Anyone else have a mistaken lyric they want to share?
