This is just a segment of a larger dream, but I don't remember the rest at all…
I was walking through Washington Square Park. (For those of you who aren't familiar with the area, this is a seedy, touristy park in the middle of the NYU area of New York City.) I happened to pass by a man who was playing catch with his dog on one of the lawns. This would not have been an uncommon sight, except that the man was throwing a lit cigar instead of a Frisbee™. As I watched, the dog leaped and caught it in its mouth. Gripping the lit end of the cigar in its teeth, the dog pranced over to its owner. I watched the man take the cigar from the dog's mouth, and felt sorry for the animal. The game looked very unpleasant to me, and it seemed that the gathering crowd of observers agreed.
I guess I started feeling self-conscious or something, because I stopped staring and walked away. as I left, I noticed several dozen smoldering cigar butts sticking in the ground nearby. I guess the cigar game must have been going on for hours…
