One of my favorite video games of all-time is the original 'Super Mario Bros.' for the Nintendo Entertainment System. The franchise has exploded for Nintendo with several games spanning 25 years.
The catchy theme from the original game has been incorporated in many of the newer games, including 'New Super Mario Bros. Wii,' and has become a fan favorite. But the fans are not limited to people. Check out a bird chirping out this infectious tune after the jump!
