Real Life Mario: link
I'm not a big fan of plays, but this one is hilarious for those who have already played any Mario game, specially the old ones!
Real Life The Sims: link
Hilarious too!
Here are a few good clips of the famous Mario theme song played in different instruments:
2 guitars at once (only one guitarist!): link
A must see! This guitarist also plays other songs using two guitars, including the Simpsons theme! :)
11-string bass: link
That bass guitar looks a bit scary, but this performance is kinda funny... I love the final bit!
Beatbox and flute (at the same time!): link
In the beginning, it seems a bit boring... But when the beatbox begins, it gets really catchy!
I hope you guys enjoy the videos!
