Red Skelton had the Homer and Heathcliff skits on his show and my favorite was the one where they are flying over water and one says to the other, "oh look at the people on that boat. They're looking up at us." and the other responds, "Must the ship of fools."
Growing up the sea, we all wore seagull splatter along with the boats. Now they come inshore and are seen feeding in the parking lots on the trash & litter left by the slobs too lazy to find a trash can.
Old time fishing boats used seagulls to locate where fish where feeding at the surface.
