What can't we do?

I just got back from Brčko district, Bosnia, where I saw this confusing sign at a gas station. Can anyone tell what specifically is being banned here?

I get the fire one, but what is that other thing? A seal? A vacuum? An arthropod?

Be cool... not celluloidal

I snapped this somewhere in Japan. I can't remember where. It doesn't matter! And where can I find such a small horse? In Japan, of course. A horse! Of course.

Hi, the Tom Stallione here. I saw this sign next to a pond in Richmond Park in London where me and Ruby Tenneco were bothering the ducks and their duckling younglings.

Yeky!
