Amusing accident

So today I was adding content to a javascript tutorial written by a co-worker. I wrote and tested quite a bit of code before I noticed that in one line, my co-worker had written a URL. It wasn't in a string, nor a regular expression, nor it was commented out. I assume he meant to comment it out, but it was there in its own line between two other functions, kinda like so:

function example1() {/*...*/}
http://www.domain.com/page/1/lorem/ipsum/
function example2() {/*...*/}

It's amusing how he accidentally wrote perfectly valid javascript code and probably isn't even aware how that line is actually a label (used for goto statements) followed by a comment.
