This song from Austin's Joe McDermott is so over the top -- the AutoTune, the rapid stylistic changes, the "K to the I to the T T Y" -- that you would think that there's no way the video could top it.
You'd be wrong, of course, as it's just a giant LOLcat video. Or at least, it's what I believe a giant LOLcat video would look like if I bothered to search YouTube for LOLcat videos, of which I'm sure there are tens of thousands. Which I don't. I swear.
If you watch just one LOLcat video this year, make it this one.
