Oh please let this be true, please let it be true! According to the TVGuide article I read, Neil Patrick Harris is in talks with Ryan Murphy to be a guest star on the Golden Globe winning comedy in a episode to be directed by Joss Whedon(Buffy the Vampire Slayer, Firefly, Dollhouse.) The legend, wait for it, -ary Barney Stinson would have a role especially created for him, which would include singing and dancing (naturally). Whedon and Harris previously worked on the popular internet Musical Dr. Horrible’s Sing-Along Blog.
Anyone who doubts Harris’ ability need only watch his latest musical performance, which if you haven’t seen you can view below.
