Because the phrase love at first sight can be so wrapped up in that one line. I’m not sure what attracts me to that line – I don’t believe in love at first sight. I believe that you can think that oh yes, someone is attractive or you wouldn’t touch that other person with a ten foot pole. But the line is nice, and here are some the lyrics that go around it.

When you can fall for chains of silver, you can fall for chains of gold,
You can fall for pretty strangers and the promises they hold.
You promised me everything, you promised me thick and thin, yeah!
Now you just say, “Oh Romeo? Yeah, you know I used to have a scene with him”

“Romeo and Juliet” by Dire Straits
