Don't forget, regular expressions in Ruby are objects (...well, yes, 
everything in Ruby is objects...). So, you could do something like:

YOUTUBE_PARSER = Regexp.(/\w+$/)

...

url[YOUTUBE_PARSER]

That way, if Youtube ever does change their naming scheme, you only have 
to change one line of code (and that line can be put right up on the top 
of your listing).

Hope that helps a bit!
