Somebody once told me the world was macaroni lyrics

Somebody once told me the world was macaroni
So I took a bite out of a tree
It tasted kind of funny so I spit it at a bunny
And the bunny started cursing at me
1000 years later the bunny was Darth Vader
And he threw his light saber at me
It missed me by a meter and then hit Justin Bieber
And now I need a new pair of undies
