I eavesdrop, although mainly because when you're on the C-train with nothing to else distract you it's damn near impossible to block out the voices you hear. People say some interesting stuff in public though... just today there was a guy talking about all of the cities that had a warrant out for his arrest, and talking about how he would frequently sneak across the Canadian-US border. You would think that it's generally not a good idea to announce that you're a criminal in front of a train full of eavesdropping passengers, but this guy seems to think otherwise.
Also, I notice that people often underestimate just how far their voice carries. I work at a climbing gym that sometimes has schools visit and I had a coworker who would regularly comment on how hot the teachers where by "whispering" it to me. Awwkward situation to be. He would say everything from "I'd love to spank her ass" to "What an ugly cow" at a level where they could clearly hear what he was saying.
