Trick and treat.

 Oh watch those kiddies Darling 

Do teach them to beware

It is the scary season

I hope they don't get scared

Keep watch for blood red costumes

And teeth of yellow hue

Those nasty fake disguises

Do watch, they will get you

Oh dear such dreadful manners

It's such a trick or treat

To ask if you are naughty 

Depends on if you get a treat

Oh my! Do just keep walking

An adult stranger, just like that

Asking if my niece and nephew 

wants to sit up on his lap

I'm sorry, do I know you

Not a way to treat my niece 

I'm sorry but you're creepy

So I need to shout police

Oh Santa is now crying 

And his elves feel such a fail

As I had them all arrested 

They'll spend Xmas is a jail
