This is not funny in anyway, but it seems appropriate:
Lúthien: 
Iris by Goo-Goo Dolls.
And I'd give up forever to touch you . . . 
Need I go on?

Thorin and Co.:
Heigh ho, heigh ho. To Smaugie we will go.
We'll take our hoe and strike him 'low
Heigh ho, heigh ho.
Or something like that. I don't know the title and the correct lyrics.
