Lyrics
The Chipmunks:
Short people got no reason
Short people got no reason
Short people got no reason to give
They got little hands, little eyes
They walk around selling great big ties
They got little noses, tiny little teeth
They wear platform shoes
On their tiny little feet
Well I, don't want no short people
Don't want no short people 'round here
Short people are just the same as you and I
A fool such as I
All men are brothers
Until the day they die
It's a wonderful world
Don't want no short people
Don't want no short people 'round here
