I'm about to laugh right now.
I just downloaded the song "Endless Love" by the Glee Cast, where Mr.Shuster and Rachel sing a love ballad together. The scene is playing in my head and I can see the frantic look on Mr. Shuster's face, and the commentary the two are doing.
Now I can't stop laughing.

On a little serious note, "Endless Love" is a very pretty song.
