This is inertia!

It's generally a good rule of thumb to avoid arguments with the homeless. Sure, you can often end the entire argument with, "Oh yeah? Well I sleep indoors," it's often considered bad form to do so, and, ultimately, there's no real victory to be had. Besides, you never really know when they'll snap and attack. While that can happen with any argument, stereotypically speaking, it's more likely when one of the verbal sparrers is living on the streets.

Now, picture what can take place when both of the people in the argument are homeless. For added surreal viewing, picture that the argument is over quantum physics, and it ends with a skateboard to the face.

We just can't imagine it, really. Not because we can't picture two homeless people knowing enough about physics to argue quantum concepts, but mostly because we ourselves don't really have that firm of a grasp on the field, and don't think we'd be able to hold our own in such an argument. Without that knowledge base, we just feel like we're missing out. In fact, the only thing that could have made this story more bizarre to us would have been if they were not just arguing about quantum physics, but were doing so in Latin.

Still, we do have to wonder exactly what set the first man off. Did the second man call him and his mother entangled entities? Was there some sort of double slit joke made off-handedly?

Maybe they were just experimenting with Heisenberg's uncertainty principle, and things went wrong.
