That's what she said!
Sorry, couldn't help it.
Ontopic: Cool! I thought it would give you an overlap error or something. I wonder if this can be done with other bricks of it's kind... Good find.
I'm pretty sure the only reason it can be done with this is because of the way they were made. If you've ever seen them, you'll notice that you can go through the top part of the spike, so that it'll give you the impression that you're actually being impaled. So basically, even though the brick appears to be that long, that part of the brick isn't actually there. But yeah, if other bricks work like this, I assume they would work the same way.
