I don't know what good an apeture-creating gun would do me: it woun't help me decide between which is funnier between Katana 314 ("I would probably make portals inside rickety buildings, then step out of them onto a balcony...wait for a guy in an orange suit to drive by, straighten my tie, and go back through the portal, closing it behind me.") and krysalist ("Remember when you told them the cake was a lie and they were quiet and then CantFaketheFunk said not to say that? That was great"). So I'd probably just use it to get to and from work quickly. I really do have very modest ambitions...
