"The Peace Carol," sung by John Denver and The Muppets, has a chorus that sounded like this to me at first:

The branch that bears the bright holly,
The dog that rests in yonder tree,
The light that shines for all to see,
The peace of Christmas day."

Since that second line conjured up so comical and nonsensical and image, I sort of 'readjusted my ear' to listen to the song again, focusing on what similar-sounding lyric might make sense.   

I'm sure the actual lyric has a "dove," not a "dog," resting in the tree, but it still SOUNDS like "dog" to me.
