You have to go and check out Dr. Horrible's Sing-Along Blog. It stars the adorable Neil Patrick Harris (he had me at Rifftrax) as an evil scientist trying to make it into the evil league while also trying to attract the attention of a girl he's barely talked to. To stop him is his arch nemesis Captain Hammer (Firefly fame Nathan Fillon). Oh and there are some really catchy songs in there
I still can't get "It's a Brand New Day" out of my head.
