We use a CAD package at work called SolidWorks. It's neat software, but it has a few small issues. One is that you can move parts in an assembly so that they occupy the same virtual space.
Doesn't really work that way in real life, now does it?
As I moved parts in an assembly model last week they intersected in virtual space. My co-worker, who was looking over my shoulder exclaimed, "GET OUT OF MY SPACE/TIME CONTINUUM!"
Definitely geek humor.
This isn't about me
This isn't about you
This is about the space/time continuum
You're a very nice girl,
I'm a swell guy
But I'm time displaced
And if I meet myself I'll die
