Wow, kudos to Nostalgia Critic for getting Rob Paulsen and Maurice LaMarche to do this:

Poor Pinky!

Awesome! I'm amazed he got LaMarche and Paulsen to do it.

Yeah pretty amazed too. Paulsen is just awesome:

All three of them were guests at a convention in Georgia a couple months ago. LaMarche and Paulsen often get together and do improvisational Pinky and the Brain skits at conventions that they attend together. Doug was just able to take advantage of being in the right place at the right time to make this possible. LaMarche and Paulsen are certainly in on the joke and definitely had no issues with doing something like this for his show.

Brilliant stuff.

Paulsen also collaborated with Walker in the short-lived Demo Reel

I watched a few seconds and was like, "Hmm, too much like something Family Guy/Seth MacFarlane would do, https://www.youtube.com/watch?v=Jt5gafdVyNw." I can't really explain what kind of humor this is, but I think the Super Mario one is comparable to this - https://www.youtube.com/watch?v=Y4mv54lw3nM.

I don't mind bad language but this kind of dry(?) humor just doesn't click with me.

Pinky had it coming though. If not for him over the 90s, Brain would've conquered the world. We probably be kowtowing to our mice overlords right this very moment if not for Pinky. Can't say I don't know how Brain felt over the years.

I always liked the fact that Paulsen's Morte in Planescape and Anomen in BG2. hehe

+1 for the linkage, I loved PatB!

+rep for the find, but oh, my </3
