Okay, if you haven't watched Dr. Horrible's Sing-Along Blog then you simply must. The songs from this have periodically been stuck in my head since this past summer. And Neil Patrick Harris is amazing in it.
To watch the full musical, go here: http://www.hulu.com/watch/28343/dr-horribles-sing-along-blog
Please do watch it...because it is hahahahilarious.
Hope you're having a happy Thursday! :)
