Here's a description: Star Trek's Leonard Nimoy sings a ditty entitled "The Ballad of Bilbo Baggins". Enjoy!
Thanks to pelayo for uploading this video.
From what I've read in the comments, a third of users were laughing their asses off, another third of users were saying "This is highly illogical" (in those exact words), while the rest were going "what the hell was Nimoy smoking?" (just cigarettes, I believe). A good mix of wit and honesty if you ask me.
As for myself, I'm still trying to get a hold on this and let it sink in. :)
