Yeah, actually this happened two years ago. The catcher was talking to everyone when they were up at the plate... eventually, the ump talked to him and told him to stop... after that I didn't hear a thing. 
To be quite honest, it can be quite distracting and well rude. So, if I came a cross a guy doing that I would be nice and tell him, "hey dude, just stop while your still behind in the game man..." Most of the time they don't talk to much because I have a tendency to tip some strikes (not on purpose mind you...) But I think that they think I pretty mean or something. lol
