I bet fish probably laugh at and talk about humans and how lame our boats and submarines are compared to how they get around in the water... When they get drunk they probably talk about our swimming ability compared to theirs which has to be full of whatever the fish version of off color humor is ...

They're laughing right up to the point that they're in my boat and in the livewell. It's all downhill from there.
