I was on the J train today in Brooklyn. Got on, sat down, a few people were glancing in my direction and were amused. I was uncomfortable but eventually looked to my right and realized they were amused by these 3 pigeons on the train car. The pigeons walked around a little, pecked at some food. Then when we were slowing down to the stop, the three pigeons walked toward the doors, congregated, and made an orderly exit. I guess that was their stop.
