Alright, a man standing in a middle of the sidewalk was looking up at the sky. A second man comes along, sees the first man looking at the sky, and looks up trying to see what the other guys looking at. Some other people walk by, see the people looking up at the sky, and also try to figure out what they're looking at. Finally, the second man says to the first, "What are we looking at?", and the first man replies, "I don't know about all you guys, but I have a nosebleed."
