I've watched several online commentaries on this song, and I find myself wondering what attributes make some videos go viral. This is a goofy song in a sea of other goofy songs. Yet, something about it excites people to forward links to their friends.

And it's that forwarding that leads to viral status.

Is it the common denominator of animal noises? We've all either had or seen those books and toys that teach kids to differentiate animals based on the noises they make.

Is it because the song is based around a question, and we are intrigued by unknown and speculative answers?

Is it the absurdity of the presentation?

The energy?

The eye candy?

The CGI?

what do YOU think?
