Is it ok

 To scratch my ass

Do I

 Die in the movie 

We all gonna laugh

 Right 

And the director

 Says  cut and that's a wrap 

When the bad movie is

 Over 

On the

 Other side of the wall

I'm sure it's a

 Stinky crackhead bitch steering in my face 

Everytime

 I look in the mirror 

I was hoping they'd

 Check back there again just in case something crawled back there and died 

I guess

 In the crawl space 

The maintenance

 Man said they were working behind the mirror
