I personally think this joke works better said than read, so tell it to your friends.
*****
It was Halloween. Wind whistled through the trees. Snow coated the ground (let's be biased to the northern hemisphere, because here in Australia, it's more like "brown snakes lay waiting for their prey", and that just doesn't have the same effect. ANYWAY…).
A strange figure approached Pirate's swoop. Eventually it reached the imposing front door.
"Knock knock?"
Alanna crept downstairs holding a candle. The stone floor was cold. Shadows leapt at her. The house creaked and groaned as if with a life of its own.
"Who's there?" she asked, glancing through the peephole. She recoiled as she spotted the visitor.
The visitor was Aly, but Alanna failed to recognise her daughter. Well, she was dressed in a cow costume. Go figure.
In the spirit of Halloween, Aly replied "I am the interrupting demon-cow!!!!!"
Oh boy, thought Alanna as she retrieved a basket of lollies from behind a pot plant. I hate trick-or-treat-ing.
She sighed, and said resignedly, "The interrupting de-"
"MOOOOOOOOOOOOOOOOOHAHAHAHAHA!!!!!!!!!!!!!"

A friend told me this joke a few days ago, just in time for Halloween! The original joke that I was told just had a cow that ended up saying moo, but with a spooky theme I altered things to make demon-cow + mooo(mu)haha. I am actually quite pleased with having given this joke a new twist; it works well at this time of year. Don't mind me, I'm feeling original. :P
Happy Halloween! :) no wait, evil smiley!! }:) }:] }:[ the last one is a vampire smiley. Enjoy the fangs!!!!!! (to say noting of the monobrow!) }:[[[[[[[[[
