box of crayons

As I was walking home from school one day
A lady gave me some crayons
She said to be careful the powers are in your mind boy
Some were missing that ruined my plans

There was red, green and blue
If I mix them together
Will they own colors be true
But will they stay like that forever

Red + blue=purple
Green + red = yellow
All these colors make me want to burple
And eat some jello

I guess this lady knew what she was saying
For my color mixing was paying
