"Yeah," James says, "I get it now...I've done a little interdimensional travel myself. I found a world where I'm an actor in a show about a serial killer...another where I am a serial killer...and my personal favorite...the one where everything's made out of something called Nerf...you can jump out of airplanes...off of buildings...and you never even get a scratch! I'm actually planning a trip there soon."
