"Practice Makes Perfect"—Mario Teaches Typing Rap

This is as obscure as things get.  A 1992 typing-teaching game starring Mario and friends.

But if you slipped the CD-ROM into a regular music CD player, you'd get to hear this hidden rap track.

Pretty funny, huh?  1992 Mario Typing Game (HIDDEN) Rappity Rap Song's gotta be a riot, right?  The crazy thing is how shockingly GOOD it is.

It's really well-produced and not the complete embarrassment you'd expect from this.

PRESS PLAY.  I dare you.
