Is there any way of stripping the sound off a youtube clip?

[alexthecheese]

I'm trying to get the audio off this little clip, as I'd really love to have it as a text message sound. Ridiculous I know, I just think it would be funny.

Is there a program to do this, or could someone do it for me?

Audacity (use the record what you hear option).
