I was involved in some sort of thrilling hostage situation at a public library where I worked. I did the IT support and someone was holding me and my staff at gunpoint. The library was a huge circular tower, maybe 30 floors, and were somewhere around floor 23 and I needed to do something to a server on the 26th floor. The gunmen were controlling exactly what I could do, but they also needed me so they were letting me on the server a bit.
Somehow I "escaped" and went down to the street level. The front door of the library was a giant bank vault door that opened inward. There was a small elephant that they kept chained just inside the doorway; she was trained to close the door when people left. The library was deserted and I left, but freed the elephant. It ran out of the building and into the streets, and also a tiger appeared from somewhere.
