Grumpy sailboater launching next to us kept mumbling remarks but I just kept ignoring him which really made it worse. He yells " HEY!! - You deaf from the noise that boat makes?" - "Its boats like yours that give boating a bad name!" I just looked at him and said - LOL,- I wasn't aware that boating had a bad name! He goes - " I'm calling the Coast Guard on you smart azz".
