Three human pirates at a Fishman bar were drinking and being loud. A fishwoman walked by, the leader of the three noticed her. "Hey, fish girl!"

"Yes?..", she answered. The captain smiled pervertly.., "We want a special service!". She turned to them. "I'm sorry. We don't do that sort of thing.", she uncomfortably said. He cocked a brow..* "Don't be such a snob! We know how you fishman are!". The other fishmen there looked at the group,looking offended. It was dead silent.. The guy stood up, "What? Does anyone have something to say?!".He took his blade from the hilt. The rest of the people there went back to what they were doing.. It was pitiful. His crew laughed.
