Just fill in the blanks and show us what that looks like!
For example:
It's My Party and I'll Cry if I want to /
It's My Bath and I'll Fill it with Spaghetti and Meatballs if I want to /
It's My Dream and I'll Sleep Forever if I want to /
It's My Back Yard and I'll Build a Gothic Tower in it if I want to
You get the picture, now make it!
Go serious, go funny, go absurd, go dark, go you.
And most importantly - Have fun.
