The Mario head is a meme that originated in Mario Teaches Typing games. He is Mario‘s head that floats around and teaches you how to type. What made it a meme is when in Mario Teaches Typing 2, he says, “I'm-a going to fly for you.” And then he flies and makes a weird sound. This sound effect has been used in a lot of YouTube Poops and many other funny things. The Mario Head is also the origin of the "Hey Stinky" line.
