We all dread a knock on the front door. Why? Because it usually means someone is going to try to sell you something. I think I found the perfect cure for those "door knockers".

This actually an ad for a New Zealand Electric Company and it's brilliant! Imagine doing this to the strangers coming to your house trying to sell you something. They won't after they experience something like this.

The great thing is...how fun would this be for Halloween? Yeah, I know! Halloween is just around the corner and this would be a most Awesome prank to pull off. Not quite sure how to pull this one off without sawing a whole in your front door and ruining it, but it would be fun. Hmmm, I can't help but think, "I don't really need my front door that bad do I?"

Anyway, It is a great little prank. Enjoy.
