I need a drink [bar - open]
Peter Venkman wasn't especially smart - not for a scientist, anyway - but he had wits to spare. He had also been around the block a few times, cosmically speaking. He'd been to a few creepy, alien dimensions, he'd traveled through time a little, he'd even been to Hell once or twice. "Not a good vacation spot. Let's just leave it at that."
This afternoon, he walked out the front door of the old firehouse - the location of the original Ghostbusters Inc., and currently the global headquarters of Ghostbusters International - and discovered that the deli across the street was now some kind of head shop, the cars on the street were from a variety of different eras (including the near future, apparently) and the skyline of the city was dramatically different. It wasn't much of a leap, then, to assume he'd ended up in an alternate universe of some kind. Maybe something was taking bits and pieces from different worlds and eras and putting them together. Kind of like a hot dog.
He quickly turned around and was relieved to see the firehouse still there. A quick inventory revealed that the equipment - the ECTO-1, the containment grid, and a few proton packs and traps - were still there. No people, however. Damn. Looks like he'd have to hire a new receptionist.
There was a bar across the street. What better place to find out about this world than to talk to the people? And what better time to talk to them than when they're buzzed?
"Hey, barkeep. What kind of booze you serve in this dimension?"
