We have off-campus eating, and as for loose animals in the school, we had a monitor lizard running loose in 6th grade. My Social Studies teacher had a room full of animals, monitor lizards, tons of fish, frogs, ect. And one of the students who was feeding the lizard the mice forgot to close the lid, and the thing took off into the halls, we all chased it, and I managed to pull a Steve Irwin, and grabbed it behind the neck, while the teacher grabbed it's legs so it wouldn't claw the fuck out of me.
