SupperMarioBroth is a fantastic blog. There's stuff like this on there constantly. The one from the other day about how AI in Mario Kart will clip through bananas if they're far away from you was amazing.
Wow, I've been thinking about this game a lot over the last two days, as I downloaded the pipe entering sound as a text message notification. I beat this game many times when I was a kid, unlocking every secret the game offered. Yet, somehow, I never did this. I think it's time for another play-through of this classic. I need to take out some Big Boos.
The other gif of Mario spin kicking...never knew that either. Pretty awesome.
